I think it's not difficult, because in AToW you just have attributes and skills (like in Genesis). The traits can exist in Genesis because they don't require rolling a dice, so positive and negative traits can be used directly in general (having reputation, access to equipment, be a noble or having an enemy is not system dependent).
Beware, the Genesis system have a cinematic and somewhat heroic mood. This may change a lot the feeling of the grittier BattleTech Universe. But sure, you can :)
