Changing Characters

This may be a stupid question, but I've done some searching and come up empty so I figure I'll pose the question to you fine folks. If I'm playing the game with Sully and decide midway through that I'd like to play as Mike, is it necessary to quit out of the game to do the swap or can I simply change them on the fly, while the game is running? Obviously I'd save prior to trying the latter but I'm not sure if it's a viable option. Infinity's website doesn't even list it under the FAQ section.

As far as I've seen you can swap in game.

You can swap on the fly. Ive done it alot of times..

Just switch the figurines wherever you are. I was nervous the first time I did it too. Lol.

Thanks, guys! I didn't want to risk messing up the game when I found the Cars vault but I was very tempted to swap Holly and Lightning for Mater and Francesco.
