Maybe just have assisting Drones work like the First Aid Kit mechanics? Take the lower of Pilot/Skillset and give that rating value as a flat dice pool bonus, even if that ends up being mathematically better/bigger bonus than the probable outcome of having used the teamwork rules instead?
That's exactly what I was thinking when I mentioned the Medkit in my first post (because as far as I can tell, a Medkit has a drone-brain built to assist the user, or even perform the task itself if wireless) so it's the closest thing we have to an example on how it might work.
Though personally, I wouldn't go with the full pilot/skillset bonus myself. I'd recommend half the Skillsoft alone, rounded up under normal circumstances. Medkits are specifically designed and programmed to assist someone at X rating. Drone AI's are not specifically designed/programmed to do so (unless they specifically are programmed to, then yeah, the full Skill would apply like a Medkit rating). I would also recommend differentiating a drone having X skill, and having X "assist" skill. They could have both, but they're separate programs, because of how the drone would implement them.
In my opinion, that seems reasonable, without being overpowered. These are just my thoughts though, and I'm open to alternatives. I'm not locked into any of these.
