Well that wouldn't be blunt to opp/lead blunt. What you're describing would be blunt to stalefish, or vice versa. And honestly, it wouldn't look that cool. You really wouldn't be able to tell if they did it because the rider would only move his hand a couple inches to the other ski.
UNLESS, he/she was doing an iron-cross true tail, and then went to uncrossed-stalefish. That'd be dope.
