Trying to clear up the reloading clutter, and use up wads & hulls I generally dont use. Must have 500+ black RGL's, couple hundred Federals/Estates. Mostly loading just 2 1/2" shells for 16's now.

Those are pretty comparable wads and at the pressure you're running I think you could try the swap without blowing anything up. It would be good to run it through a chronograph and see if the velocity changes much.
