but what if I added thickness to it and soldered in Cherry switches? I suppose all the key sizes are wacky.
It might help if you posted your exact model. However if it's anything like the Apple aluminium keyboards I've used I think it would be challenging, especially on the top and bottom rows. Apple function keys are small and down close to the number row. On the bottom, their ctrl, alt, meta and space bar sizes and positions might not match the keys you're cannibalising... unless, that is, you're planning to mount the Apple scissor-switch keycaps on top of the new cherry switches. It would be tricky to get that working smoothly. And what about stabilisers on the larger keys -- where would they mount?
I think this would be quite a tricky mod. If you could get it all working that would be insane... maybe in a good way, but not necessarily. :smile:
