If Shran joined the Enterprise crew as an consultant I would have created a position for him similar to that of Worf's on Deep Space Nine as Strategic Operations Officer (or whatever it was). Or perhaps like T'Pol's original liaison type role. I think Shran would have wanted to be as hands on as possible.
I'm also fond of the idea that was suggested regarding the origin of the Borg Queen and Alice Kringe playing a Starfleet science or medical tech or whatever it was.
Really? I gotta say of the season 5 ideas I read about, this is the one I like the least. It sounds a little too "Earth-centric" to have some human become the Borg Queen when the Borg are supposed to be on the other side of the galaxy at this point.
Other other ideas they were considering:
-On the idea of Shran becoming a crew member, I can't imagine anyone not liking that. It would be extremely exciting to see Jeffrey Combs' name added to the opening credits.
(Still, you'd have to feel a bit for Anthony Montgomery and Linda Park, having ANOTHER actor coming in to upstage them.)
-I liked the idea of going to Stratos.
-I also liked the proposed idea of bringing back Flint, presumably under another alias. Perhaps they could've cast Tim Daly to assume his late father's role.
-Since I grew up never seeing the animated series and assuming it wasn't canon, I tend to be rather indifferent to the idea of introducing elements from it, like the Kzinti. I'm not necessarily opposed. I could just take it or leave it.
-It's hard to know what to do with the idea of the first starbase, since presumably there'd be more to it that just that.
-Doing more mirror universe episodes sound okay (more Defiant, hopefully, and maybe a mirror Shran), but I really think DS9 went to that well a few too many times. In fact it was because of that, I was initially dubious when I heard Enterprise would be doing it, though I later reconsidered, of course. Still, as fun as it seems to be for the actors and writers, I think there's a risk of having too much.
Things I would've liked to see:
-Introducing more aliens either from TOS or species we know to be future Fed members i.e. Betazoids, Trill (early Dax host?), Deltans, Efrosians, Grazerites, etc.
-I thought they should bring back the character of Admiral Valdore, if for no other reason than to let improve his standing somehow. (It's hard to believe this guy would get a ship named after him, given the way the trilogy played out).
-I'd love to see if they could find a way to show a Talosian (the ORIGINAL "alien of the week"), albeit without the regulars seeing them of course. Since the Romulans were kidnapping telepathic aliens to control ships, it could work. It'd be neat if they had a woman play the character but be dubbed by a man, just like in "The Cage".
-More Tholians, maybe?
-What about one of the black/white aliens from "Let That Be Your Last Battlefield"? (Not necessarily the two individuals from that episode).
-It would be interesting to visit the planet from "A Private Little War" and see a Mugato. Then again, furry creatures are supposedly a pain in the a$$ to render in CG (i.e. why the sehlat in "The Forge" was barely glimpsed), but maybe the planet's fanon name of Neural could finally make it into canon.
