I'm a big WACKo fam myself. In fact, I was a fan of the West Coast team long before I was a fan of the "main" Avengers.
What it would take would be a focus significantly different from the "main" Avengers. I haven't read Avengers in a LONG time, so I don't know what that would be.
I'd be excited for a book with any/all of your suggestions.
In addition: USAgent, Dr Demonicus and/or the Pacific Overlords, and some iteration of the Phantom Rider.
I too was always a fan of the West Coast Avengers, and I hate what they did to the main Avengers in the last few years - to expand the Avengers so much - nearly every single socalled Superhero in the MU is now an Avenger! I would enjoy to see the old roster back, including Living Lightning and the Agent an Jim Hammond, it would be great, if it is a serious comic not like the GLA (tough I like the original GLA too!!) or other funstyle comic, BUT I wish they would bring together the old AND new Whackos to one "big" Team, that grows together and then bring in all the old foes and villains from the old West Coast Avengers series! I don't know why, but I liked that freak Cybertooth and always hoped, he comes back and ... becomes an Avenger ...
Maybe bring in characters from Force Works too ...
But please, not again and again and again Deadpool again everywhere and in every fifth issue!
