I want the Alpha's to learn how to take the form of the Loup.
Because having a couple of those with a fully-functioning human mind behind them would be awesome. And terrifying. Awesifying.
I think Fight Night would be a good time to bring back Tera West. I doubt there's much room for her in Peace Talks or Mirror, Mirror (though maybe she came back in the Mirrorverse to protect the Alphas). Anywho, it'd be cool to see the relationship change from Fool Moon to current Will/Georgia. With all their maturity, and experimentation (as seen in Aftermath), I could see Tera West teaching the remaining Alphas some new techniques, possibly becoming something as impressive as a Loup Garou—though not specifically Loupy, because, as I understand it, there are certain circumstances that must be fulfilled to make one.
Side note, I've thought about Tera West and the Alphas freeing the Fenris Wolf mantle from Gleipnir to assume it themselves, and kicking off modern-day Ragnarok. In this instance, the mantle is actually Fenrir, Garm, and Hati Hroovitnisson (all the named wolves/wargs in Norse mythology, which some insist are all just aspects of Fenrir), and the Alphas assume them all, forming a Norse Mythology Pack. T'would be cool, if only because I haven't seen anyone do much with Fenrir in recent years, except those Everworld children's (young adult? They're a bit too short for that, so mid-grade, probably) books, and a rather awesomely awful apocalypse novel titled A.D. 999, which was
very concerned with being taken seriously. (As a further tangent, I don't think the author of that book ever wrote anything again, but I remember having fun reading it once I turned my brain off. The book blended Revelations and Ragnarok, literally interpreting the Signs of the Apocalypse, and even brought back King Arthur and the Lost Tribes of Israel for the penultimate battle. Copies are hard to come by, as far as I can recall, but if you can find it at your library, it's worth a read if you like end-times fiction and Dark Ages Europe.)

I could get behind that. Robo-Bob. RoBob? Sure. It would certainly set the stage for hilarity (Bob's ecto-flesh reverting to goo from being trapped in a circle temporarily, leaving him as an orange glowing skeleton running around Chicago, for example). I doubt Jim would want this to happen, as Bob can be totally gamebreaking if he gave him too much freedom.
To the OP question: Carlos or Elaine. Carlos because he gets injured in every book (usually pretty badly), and I want to see him bring the pain without taking knives to the gut and the knee for his trouble. Plus I like his disintegration shield, and applied appropriately, I could see that being... messy.
Elaine because I sympathize with her character quite a bit. Both times we've seen her, she's suffered enormously. Yes, I count Summer Knight and her "betrayal" arc, because she was in a nearly impossible situation and did what she could to make things right. She's been on the road to redemption for a while, and I'd like to see her unload on some bad guys from a position of real power.
