Your current frame has a 68mm English threaded bb. It is not limited to a square taper bottom bracket. You say you want to put a full Shimano 105 group on the bike, I assume that includes 105 cranks. If so, it is no problem, the Shimano Hollowtech II outboard bearings will work fine, and are what you need for a modern Shimano 105 crankset.
