I send Tali back for the very same reason, both qualify very well for repairing the ship (Tali should be the better choice even, because she's a more proficient Engineer, so to speak off). I usually have all of the crew surviving anyway, because after playing the Suicide Mission a handful of times it's hard not to know which squadmates are fitting for which role, so I don't need to "save" anyone by sending them off to the Ship.
