He may come on weird at times, but I think he may have a (small) point
on this one.

Think about that one for a moment.

OK......
It'd work. That's not to say it would be a net saving of energy, but the
anti-roll fins already do their thing at the cost of added drag.
"Programming" them to net forward thrust might not be possible except at low
speeds, and increased roll (although they would still dampen it), but it
would work.
