What about for ALPS? I assume there's a restriction then?
I believe you are not familiar with alps switches
If you want to use alps switches and stabilizers, you "should" make switch mount plate very specific. No optional placement is allowed.
So, when this GB starts, anyone want to use alps switches have to set(draw,fix whatever) their own layout and attach it on order.
And, that's why I charge more price for alps switch plate.
And for your question,
If you have proper keycaps, you can order whatever layout you want.
