BGA is indeed a PITA but not a complete show stopper. I haven't mounted one myself, only "reflowed"[*] twice (iBook) and removed a few times ;-) but with a proper rework station and some experience that should be fine too.

* - far from proper reflow, just heated with an IR gun until solder melted enough
