Why would you want to do that? One of the nicest things about Fallout is the fact that you can create your own character. If you're going to play with someone else's saved game, you're going to have to play with his character also.
If you really hate the temple of trials, just run as quickly as you can to each exit. You'll only have to fight maybe seven or eight ants along the way, that's all. It shouldn't take more than what? Five minutes? And don't fight Cameron, just steal his key or talk him out of fighting (speech check). It couldn't be more simple than that...
