I like your idea, Pro, with some reservations: If these are indeed "streamlined" stories, then let's not let them take very long. I don't want to have the team away from earth for a year (our time) because that would put a cramp in a lot of off-team character development I'd like to do. Also, I do plan on alternating between Mason Templar and Axel Magus once the boy comes into his own as a sorcerer, and I won't be able to switch between characters from story to story if it takes too long to write this story arc you propose. That's not a problem if it's done in a relatively shorter time than our usual slow-moving stories of the last two years, as I won't be using Axel as a Vanguard member until several stories from now, but I can foresee it getting excruciatingly boring if we find the team stranded out in space and everyone runs out of ideas to keep the team occupied. This idea could really go anywhere, though, so I'm more willing to bet that it could free up a lot of imaginary juices by getting the team away from the framework of their headquarters and their "posse" of supporting characters which continues to naturally grow story-by-story as we give "lives" to the team members.
So anyway, I'm for doing it sooner than later IF it's written in a more streamlined way and done much more quickly than our usual lazy, half-assed pace.
