Yeah, I do exactly that: change strings on one, play it as the main for one show, then it's the backup for the next. That way I'm only dealing with one guitar restring between gigs. Two gigs (about 3 hours playing each) plus practice time in between is enough on a set of strings for me. The one that broke was after three gigs.Once in 100 is enough for me to always have two. And to feel less guilty about it, they swap roles (main/backup) for a set.
