DC seems to be letting P&G set up the characters associated with the Freedom Fighters for a revival of the group.
Now that DC is a 'new' universe, I would like to see a revival of the Seven Soldiers. Maybe following a similar path: introductory limited series for each character (although Green Arrow already has a series) and maybe a continuing 'master villain' in the background of each limited series leading to a 7S series down the line.
I would even take them on their own Earth or on Earth 2.
Vigilante - yep, use the cowboy version. Something about a cowboy themed hero operating in modern times that I like.
Shining Knight - Sir Justin. If one Earth one, time him in with Justine. If Roy Harper isn't used, maybe give him a sidekick, Squire.
Green Arrow & Roy Harper - Use the current versions or just Ollie without Speedy.
Crimson Avenger - either version, the Shadow-esque version or the red suited one.
Star Spangled Kid & Stripesy - A kid more intelligent than the adult working with him is one that I like.
I liked these characters in the JLA/JSA crossover. ANd I just finished reading all three Seven Soldiers Archives and think this could easily be tweaked to work in the current market.
