When Mike Miller comes back does it make sense for Arroyo to start at PG?

I think that Lebron should run the point, Wade the shooting guard, and Miller the small forward. Wade and Lebron are great iso players but not great shooters so don't think they need a traditional point guard to start with them. Plus basketball is about mismatches. If they use that backcourt against Orlando, LA, and Boston that would mean Nelson, Rondo, Fisher would have to defend either Wade or Miller and none of these guys would be able to do it one on one.
