stuck BB idea

I have this FSA BB that is stuck on the drive side cup. That would be a reverse threaded external BB. It has been on the indoor trainer and actually works but I want to get a new R7000 crankset.
I have tried the usual BB tool but it will not budge and I chewed the outside of the notches trying. So now my thought is get a hose clamp and put it around the BB cup. Then get it really tight. Then take a large pipe wrench and set it up to grab the clamp threading as a point of pressure and give it the big turn.
What do you thing of this idea. I don't try getting some penetrating oil in around too much work. I just want to give this one big swipe with the pipe wrench. If the frame goes south doesn't matter.
