So pilot really represents something specific, and while the Prototype-style idea would represent that, its a bit of a stretch for a power that zerg would use -- zerg don't hijack a body, they infest it and it drives itself under control of the swarm, so that falls more directly under the command skill. I am also not terribly worried about the pilot skill as some infested still have uses for it. The first is for Agents of the Swarm who go into Doppleganger builds using the upcoming Suppress Infestation mutations drive just like any normal Terran. But also there are infestation powers that allow you to infest and use standard terran constructs and (importantly for Agents of the Swarm) vehicles -- so you have infested Terrans driving infested siege tanks and piloting infested wraiths. Not every infested will (or should) be a skilled pilot, but those few pilots are still incredibly important to the swarm, especially when partnered with an infested evolutionist or the living plagues from the december bonus content who both will likely become skill enough at infestation powers to make controllable infested vehicles eventually. So overall infested don't have as many uses for pilot as normal Terrans as it is a much more niche skill and is only really usable for infested Agents of the Swarm. For those characters though, they gain the full benefit of the skill as it was designed for Terran PC's. Thus for infested characters, pilot is a crucially important skill limited to a few characters that can possibly use it just like psionics for regular Terrans. Now all of this is just my perspective on the matter, but I don't really feel that anything special needs to be done for pilot because the few characters who do use it gain the full benefits of the skill unlike the medicine skill in an infested party. However let us know if you still feel this is too limited a use for a core skill and we can keep the discussion rolling!
