has someone checked to see of putting a 1.0 backstrap on a 2.0 frame and vice versa is possible. Blockbuster trade decision 'tween me and lonestar outlaw hanging in the balance 

Same here. I've interchanged tools and grips without issue.I purchased a FDE Gen 1 small backstrap to try on my Gen 2 and it went on fine and stays in place using the only frame tool I have, the Gen 2 (or 2.0 if you prefer) I thought the 2.0 grip texture might prove too much after a few hundred rounds, but it didn't.
