the extra range might already be baked into their future profiles
crane gunners on lanterns have 36" of range, I doubt they would need extra range

as for the extra rank, I don't really see the crane gunners, presented as teams like in pic related, would have a rule to fire on an extra rank
but I can see them getting a rule to fire twice per turn or move an fire once per game, like for the ogre loader, thanks to the second guy helping out
