what do you mean scoot the hub over?
some cranksets put their inner ring way far out, some don't. likely it's an issue with the crankset, as most flip/flop hubs and bb are pretty standard. if you told us more about the frame, we'd know better.
it's not worth the shenanigans of messing with cranks and bb, you're right. unfortunately, it's more than likely going to come to that.
