Took another look, wouldn't be hard for someone with an electric saw to saw it off, because I did manage to get about 1/4 out (yeh I know I said 3/4 below :P).
Don't think you can get a drill to line up with that bolt, the metal frame is in the way. Anyhow, its not rattling or loose and the handle is firm, so I'll worry about it later
I think if someone wants to get into the car, there are easier and quicker ways to do it.
Door trim back on, put some new tabs in there, and its now solid as a rock. Those tabs are like gold...$4 each!
