Perhaps it might be worth checking the Society ProtoMechs (or "Z" variants) when their conversions are being done, to see if that particular class was ever used by a "standard" Clan (such as the Coyotes).
If it was (such as the Sprite and Hobgoblin, both of which are listed on the 3085 Homeworld ProtoMech RATs in WoR:S), it could be offered in AS with the assumption of a five-proto Point.
However, if it was a variant which no Clan ever adopted (such as the Procyon Z or Roc Z, which even the Coyotes don't have on their 3072 ProtoMech RAT), it could instead be done up using Society force organization templates (perhaps as a three-proto Un).
Or, perhaps the units or Z-variants that only served in the Society could be skipped for the time being, and revisited once the Wars of Reaving are handled in a future AS PDF supplement. (At which point, other Society-specific Unit Cards might be offered, based on their descriptions in WoR:S?)
EDIT: And speaking of non-standard force organizations, how many BA troopers are in a single squad, as used by the Marians? Do the Legions use standard IS deployments for their troopers, or would a Unit Card of standard Spheroid BA squads not represent how things work in the MHAF?
I recall that on the BattleMech side of things, the Marians deploy those units in five-'Mech centuries. But how many BA troopers would equate to each BattleMech from the Legions' point of view?
