The easy answer is yes. There is no reason we can't have any number of different pet glams aside from the development time needed actually being devoted to it. The devs notoriously hate pets tho and that's just an assumption from the many many years of them being neglected and progressively erased from the game. If it was important we should have seen a Feo Ul glam in Shadowbringers where it would have made the most sense.
