High-profile modification?

[prometheus-industrial]

First of all, I wanted to say thanks so much for this design!

I'd love to use this case on a Lily58L, but I prefer high-profile cases when available. Looking at this design, it seems like it might be possible to cut an extra middle layer and put it on top of the switch plate layer to hide the sides of the keycaps better.

Do you think this would leave enough clearance for the keys on the edge to fully depress—especially with a 1.5u cap on the bottom-center thumb key? Or would the shape of the layer need to change to leave enough room for the keycaps? Also, would the standoffs need to be longer by ~3mm to accommodate this change?

Cheers,
Z
