cool, when your ready to do the BBP conversion you can just get those axles re-drilled to the proper pattern

Nope. You do not have room to put another BC on those axles. Not unless you want to have the holes welded up, and have the flanges re-machined to make them flat again. By the time you find someone to do that work properly, and pay them, it's easier, and better, to get new axles from Dr Diff. Needs new brakes too.
