I wonder if one of those MagSafe cases that basically "passthrough" the MagSafe magnets in the phone would work.

Just as well as any of the other ones for Android phones. Heck, you can even buy adhesive magnet rings to stick directly to any case or phone back, as long as you align them properly.

Absolutely. Plenty of even cheap cases have the magsafe ring to align the charger and then would work with the magsafe puck just fine.
