Legion of Super-Heroes and The Rocketeer

The Legion of Super-Heroes is a great team but can be a challenge for it's writers due to the sprawling cast.  One technique that DC has used a few times is to separate the team by time and space into different groups for long stretches.  I get a kick out of those tales because it's cool to see the Legionnaires outside of their futuristic setting and reacting to contemporary characters.  It might be interesting to see the LSH in a wartime setting, and seeing who they run into as they try not to alter history.
