I believe currently this would render the parts illegal for tournament use. A proposal has been made to allow swapping of identical pieces of parts in order to make repairs, but it has not implemented as of yet.
The main issue here is that the tip of the normal Drift driver is not the same as the tip on Bearing Drift. So, unfortunately, this wouldn’t accomplish what you are trying to do.
“Compared to its predecessors, its conical sharp tip is slightly taller, with the center protruding more; this increases height by 1.5mm.”

EDIT
Just reread your post and realized you were talking about swapping the other way. This would still be an illegal modification. You also run into the issue of the internals of Drift and Bearing Drift being different (having a bearing).
