Take this with a grain of salt, but the New Mexico bowl vs SDSU is the most likely option. (Don't like the stadium, but Albuquerque is nice enough this time of year and I enjoy a couple different science based attractions that I would go).
What does make this good though is currently the Vegas Bowl is that night on ABC, New Mexico Bowl has the earliest time slot of the day. But due to the Raiders hosting NFL Sunday night football, but they suck this year, and NFL "Flex Scheduling" moving the Raiders game to Sunday Afternoon . . . The Las Vegas Bowl would have to switch with the New Mexico for TV time slots, and BYU vs SDSU would be on ABC prime time.
TL;DR, I got a notification from someone associated with SDSU that BYU could end up in the New Mexico bowl playing against SDSU during prime time ABC. This is of course just an option, but according to him the "most likely option".
