I do this on occasion, and I am with those here who say that the swap should be arranged by the parties involved. The FA/GAs have plenty to do without wasting time trying to downgrade someone and bring the next in line up.

By the same token, I always tell the FAs what I am doing as a courtesy.
Only once have I encountered any pushback, where the FA said it wasn't my seat to give away, and that it would have to go to the next person on the upgrade list. In that case, I said, "fine", and took my seat in F.
