In the Stargate television franchise, did the shows' developers ever consider letting the Goa'uld use the Wraith as hosts? It seems like a perfectly logical NEW direction that would have at least left a way open for a new threat.
the question header and question dont match
as to the header we never see a gou'ld try to possess a wraith however we have seen a gou'ld possess at least 3 separate species humans, unas and the creature that was placed in the sarcophagus with Marduk. If the gou'ld can possess a species so dissimilar to that of its other hosts it stands to reason they could possess a wraith.
