The other thing to do as a plan B is to ask people on the plane to trade seats, often they will and remember a few seats will open up when people get upgraded for free.

But the OP has now managed to get six seats together in the back of the plane. Sitting together is, of course, their first priority. It seems unlikely that they can persuade six passengers all seated in a block of better seats to move back.
OP, you should point out to the GA that if enough people are upgraded from C+ to F, your group should have priority for the C+ seats over any medallion upgrades to C+.
