You could clamp it in vice. There is a process called back riveting
in which the rivet gun and a flush set is used to directly upset the
buck tail while the manufactured head is held against the bucking bar;
I have seen it used when someone is riveting flush rivets in thin
skins and the flush head is held against a flat plate. This would be
similar to what you propose. The key is to keep the slamming effect
to a minimum by keeping pressure through the rivet from the gun to the
bucking bar. Once the bar or the set or the rivet really move around
that is when you will have smiles at best or tool strikes at worst.
