I can recall seeing a 90 degree crossing in 9 mm gauge before but can't recall who made it. Having had a quick look on the internet it might have been made by Shinohara, but they only seem to do an N scale one - so it will be 9 mm gauge but have smaller sleepers at a closer spacing. That being said they may do one for HOn30 (HOn2.5 in some circles, also known as HOe). Shinohara seems to be mostly available in the US, but looking at the Scale Link website (http://www.scalelink.co.uk/acatalog/Shinohara_Track___Pointwork__N____Aiguillages.html you'll need to scroll down the page) they do list the 90 degree crossing for N in code 70 rail, which is not far off that used by Peco (code 75?) so they should be compatible, and Scale Link are UK based. There may also be something available from one of the European track people (Tillig, etc.) that you could use.
As to a 'kit' I don't think anyone does such things for 009, but building track from rails and copper clad sleepers is not as hard as people think, and I've built a diamond crossing (about 88 degrees) that I can push wagons through (not wiered up yet). You'll need some track gauges - N-gauge roller gauges (try SMP or the N-gauge Society, but you'll need to join the latter to buy from them) and / or some triangular gauges (the ones I use are from Micro-Engineering in the US, bought through Canada!). The rail might be quite easy as I'm sure Peco will sell you just the rail (Code 75 flat bottom) or you could strip it from some flexitrack, and for sleepers I used TT ones from 3 mm SMR. Other than that you may find a jewellers piercing saw useful for cutting the rail (though a razor saw will also do the job) and a way of accurately cutting angles to make the corners.
To be honest you may get better running from a hand-built one as this will not have any 'dead frogs' found in the ready to lay items so small 4 wheel locos should run better across the crossing, but you will need to switch them in some way so that the electrical polarities of the rails are correct for the direction of travel.
Give one a go as no one can say they can't do something until they have actually tried! Build the first one at least on a small board away from the layout to lay in place it once it is working and if it doesn't work out then you could try a bought one or rethink the layout plans.
And keep us posted on your progress. :)
I realise I have a photo I can post:

Note that all the running rails within the diamond are gapped (piercing saw cut) so all 4 corners are isolated. These will need to be switched to allow for a loco to run through.
And if you want to do dual gauge (9mm and 6 mm)

This time the rails for the 6 mm (reprisenting an 18" gauge hand worked line) are gapped to stop them shorting the 'main' line (9mm gauge) but the rails for the 9 mm are not as the narrower gauge is not powered.
I've not added check rails within the diamonds either. If I do I'll probably do so using plasticard microstrip superglued in to look like rail rather than trying to use metal rails (with all the isolation gaps needed).
In my opinion it is best to avoid any crossings in 009 if you can possiably help it, but if you can not then I think the best option is to build it yourself with full 'electrofrog' type frogs where the rails cross, just like in the photos in the previous post. Another tip is to make it so it is not quite at 90 degrees avoiding both wheels being on the gap in the rail at the same time, again like in the photos in the previous post.
However Egger-bahn made a 90 degree crossing in the 1960's. These sell for between
I think it was Atlas who did an N gauge one...

Yes indeed Blair, so do kato. But the kato one is on its own plastic ballast.
But both have dead plastic frogs, and obviously N gauge sleepers.

Tomix do one: https://m.ebay.com/itm/TOMIX-N-Scale-1324-FINE-TRACK-90-Crossing-Track-X37-90-F/152114336936?epid=1171464945&hash=item236ab894a8:g:aT4AAOSwu4BVhpyW (again N scale sleepers).
They also do a double track version and one with inset tramway track but not sure if the rail height is smaller than usual.

Again these all have dead plastic frogs.

Dead frogs are not the end of the world though. I have found that you can use insulfrog crossings but it is wise to site a mobile phone vibrator motor underneath in case anything gets stuck. I had to do that on Dean Hill as there was only one crossing that would work with my track layout.

Was this because you did not want to make your own all electrofrog crossing?

Frankly I think life is too short to build track. As we normally build one layout a year I have a lot of other things to do and, since track work is fundamental to the success of the final layout, the manufactured precision of bought in parts is vital.
The crossing we had from Peco for Dean Hill in fact never failed and I never actually used the vibrator but it was nice to know that it was available just in case of a stall. This was a DCC layout and featured slow running of four wheeled Hunslet and Baguley-Drewry diesels. It is still on circuit with another owner and you can check it out at the shows he takes it to.
By the way, Scalelink (http://www.scalelink.co.uk (http://www.scalelink.co.uk)) are the suppliers I have used for Shinohara track. The good thing about their OO9 track is that their points have a very tight radius of 150mm and have fine code 60 track work. We are planning to use this on another layout next year once the Woolthorpe Light Railway is completed.
