To those who have expressed interest thus far, and any who come along next, what alternate worlds or concepts would you like to see? Whether it just be a character you like/think is underutilized and would like to see be the focus of a reality the group visits, or a story arc from the comics you felt didn't end properly and would want to see revisited, or something from our real-world history you think would create a unique reality had it gone a different way, etc. 

While I have dozens of alternate realities already plotted out, I am interested and open to including others suggested here.
