That's exactly what's going to happen. Look at the home games..
Utah State/home opener - no chance of wearing anything but orange and white
Ark State - not significant enough to wear the grey. Will be a high profile game like UGA last year.
UF - coming off 2 losses, need any extra motivation. Think of this game sort of like last years USC game. Redemption from the previous week. This seems like the most plausible. Only issue I see here is, UF's helmets are orange.
Chat - homecoming. 100% orange and white.
Bama - No chance of screwing with that tradition. Also, don't want to go winless in the grey, which Bama is most likely a loss.
Kentucky - Maybe.
Mizzou - Very possible, but I would expect to see the alt uni earlier in the season, rather than the last home game. If going by the same plan as last year, it could be UF AND MIZZ (UGA and Vandy in 2013).
