The only thing I can see that plate doesn't do that's somewhat common these days is split space bars, if you want to cover everything?
If you're really keen the split enter where there's room for ANSI \| and a 1.25 key and 1u below it, which I've only ever seen on the GH60...
Depends if you're willing to sell the plate and tray without a PCB
Also those look like plate mount stab holes, I think with a universal plate you need PCB mount so they stay put. They may already be, I'm not an expert.
