For planning, I am with Chewy, we must think a story at a time. Don't plan the long run, because that could work for ONE writer, not for eight (more or less).
For Morrisonesque, I think of Morrison's run over JLA, that has been my best exposure to the writer. I think especially or Rock of Ages, where in a story he crammed more ideas that in a whole run of one other writer's typical comic. I think of heroes used at their best for their superpowers, for their characters, focusing over their iconic role. I think about weird smart things (like Green Arrow and Atom taking dow Darkesid)...
The opposite thing I am interested into is superheroes in the "real world", either as "normal" people with enhanced powers, or like true superheroes threated like all-round persons like usually James Robinsosn does (starman and the Golden age, for example).
The one aspect that I liked most form the first year of Vanguard was the spy game among countries for the use of metagene, that would be fun to expore properly if done by people all interested in that. But I know is much more hard than writing cosmic stuff.
But for me, there is just one thing I am really interested into, and that is the collaborative writing. If we are able to do round robin, I'll adapt even to romance, western, fantasy.
Since it seems we all agree on starting over, why don't you start to advance actual ideas for the first story? I wouldn't, as I started the last Universe, so this honour has to be reserved for some one other, this time.
