To Rojero's point, I think this would work well with nice html map with hyperlinks to areas of controlled galaxy as a backdrop.
Perhaps this can be added to the existing Legacies format?
The backdrop map would have static systems maps. If a player controls an area of the galaxy, he or she controls that specific map, and must defend it when the neighbor elects to advance.
At the beginning of a macro "turn" all empire declarations should be simultaneous, then all games resolved, and then the backdrop map adjusted.
Has possibilities?
