Possible Rev3 approach to microsoft controller boa

I was thinking that to minimize the effort involved that perhaps we could design/build our own PCB that could accept the microcontroller and wireless chip. Been reading about people using heat guns to remove SMT chips and soldering them isn't that hard.

So perhaps ultimately the only process would have to be extracting those two chips from the board - which wouldn't require any desoldering - just unscrew, heat, and replace.
