I thought of two more things:
A Rigger for a squadron, with a talent that allows you multiple Signature vehicles with a maximum total Silhouette equal to 3 + ranks in Larger Project. Ie if you’re usual maximum was Silhouette 6 you could instead have 3 Silhouette 2 Signature Vehicles or 2 Silhouette 3.
A Pack Master, Hermit with the ability to have a minion group instead of a single bonded animal.
both can be easily house ruled but a spec would be cool.
