If you're at all concerned about the presentation/them falling apart you can half-braise them for maybe 1.5 hours, but that's just an idea - it's not necessary. You're going to have to heat them through completely before you serve them anyway, so I just thought I'd mention it.
Yes, I do it all the time. Works great. The biggest challenge for me is to try to keep the slices looking nice if I transfer them from the pot to a plastic container for storage. If you have the room, you might try storing in the cooking container.
