Even if class/background/race/ability scores/etc are the same, can't you just change personality? No mechanics needed for that. Just role-playing.
Yes, but then you would have to think out some extra goals and tie-ins to the world.
I was wondering about this too, good question.
Perhaps it would be good to have some backup pre-gens ready before you start.
If one of the new players I'm introducing to D&D dies I don't want him/her to get discouraged but to pickup another character ASAP and continue playing.
Then again, what happens when you have a TPK?
"It was all a bad dream" ?
