That's absolutely fine, and in line with what we've done in previous rounds and seems to have worked well; I've currently approved TOS, TNG and AOS (and AOS-projected-forward-to-DS9 as its own thing). I probably won't get to DS9 until the weekend (I'm focusing at the moment on tags that have been added to fandoms already approved, as letting too many of those build up hits a pretty severe limitation on the AO3 interface of only displaying the first 30) but the tags for that look fine as well.
