Distributor hits Intake Manifold

The distributor is driven by a slot. Either it's in right or 180* out. He will have to reclock the intermediate shaft to do what you are talking about. If it was mine, I would just move the wires one spot around on the cap and be done with it.

Either way gets the job done. Gotta admit though, Chevy makes it a lot easier with the gear atteached to the dizzy.
