Simple: Create a separate queue for the current FOTM. In this case: high-alpha.
A player is moved to the FOTM queue if the 'Mech has at least one of the following:
- 2 Gauss or
- 2 AC/20 or
- 3 (ER)PPCs (both summed up) or
- two weapons of the three above (e.g. 1 Gauss + 1 AC/20)

I'm sure someone suggested this before -- I just cannot find it.
Anyway.. have fun!
