Definitely! That is actually quite similar to the last keyboard I designed called the Speedo but it looks like you’re putting much more thought into yours. 
I wasn’t very happy with the thumb keys on the Speedo. I think the angles I chose were a bit too aggressive and I will dial them back again if I ever get around to making a new version. Having used an Iris as a daily driver for a bit, I think the layout you’ve chosen for the thumbs would be superior.
I do indeed have some pictures!
These are from the first build which was hand-wired
These are from the second build I just finished this morning which uses a PCB. It actually has underglow but the dark red translucent material I chose for the middle layers doesn’t diffuse the light nearly as well as I had hoped it would.
