The first thing I did when I got an elite controller was to try to re map bash to a bottom paddle. I was really disappointed I couldn't. S&B is built around interrupting abilities and the button manipulation to do it is a little extreme
Not sure exactly how we could get this to work smoothly.
What I do know is we need to replace the button that toggles through quests with something, like the ability to activate synergies.
I'd prefer if we could manually assign keys.
