I like the Archie comics, but I kinda see this as a bad idea.
I mean, the stories of the comics are set in the future but they both have different ideas.
Not only that, not really much to do with a Sonic/Megaman crossover. Not only because they have different ideas, but aside from a "Robotnik and Wily team up" and possible "Sonic vs Megaman" scenario not too much to do to it. Especially for 12 parts.
