Come to think of it, would it technically be possible to install a different port (as in USB-C, or mini-USB, or whatever) instead of the horrible micro-USB port? I find conflicting statements when trying to look this up, so I assume it isn't possible, but I'd still like to know for sure.

Just to make it clear, I don't care one bit about the actual USB connectivity as I access the filesystem wirelessly anyway, all I'd want to work is the charging aspect. I wouldn't mind cutting a slightly larger hole in the plastic at all if it meant I'd get a more solid connection that wouldn't cost me a fortune having to replace it every other week.
