This is a good idea.

Depending on the amount of Serviceability the OP needs with this, I would consider adding the regulator where the subframe crossover rubber hose would be, then either running the cross-over hardline and then hose up to the carb, or running hose from the regulator up to the carb.

This would give a more stock like appearance and routing.
