might have a problem mounting the stabilizers since there won't be any cut out for them with the 7bit plate
You can probably just put switches to hold it in, and take the springs out (unless you like heavy spacebars, that is). It'd be like an expensive cherry stabilizer, I think.
I think I'll Put my spacebar where I like it (on the 7bit layout) and leave (most of) the rest of that row empty (I mean, I'll still have CTRL and ALT).
Hazeluff: I have almost the same idea for my right side. It'll be awesome! The way I see it, on "normal" setting, it'll be arrows, insert, etc. but once numlock is toggled, I can use it like a basic tenkey. I think I'll put the extra function key up at the top(since I'll have extra room), after all the F1-F12 keys are.
