108 includes 104 plus 4 media keys. I think there are also a few international layouts with more keys than US-standard, but I never got that far.

That... is a recipe for pain. Complexity of small hardware projects is basically Ackermann in the number of processors you are coordinating.... Ideally in a product you really, really want only one firmware blob to update at a time.

I don't know if alt-codes would work with this strategy.
Regardless, none of this is worth it just to avoid prototyping with a BGA or dev board. (I'm not even trying to avoid those for production; this is my day job so I'm not that afraid of big BGAs. I just don't want to ever have to solder or probe them, and the gods alone save you if you have to rework a joint!)
