Marketing it at stores would be a prob. My local shop basically sells comics and merch for the big 2. At least 4/5th of the product space is dedicated to the Big 2. A compendium aimed at new readers would not get decent product placement at my local shop. I imagine it's the same at most comic shops. The only other store in my area for comics is Barnes and Noble. But they mainly do watered down/mainstream stuff that's gonna sell tremendously. They don't take chances on indie stuff. So the problem on Erik's end would be getting retailers on the ball.
This is also a problem that Ant would face if resurrected. I highly doubt Barnes and Noble would sell Ant trades. And the local shops would have poor placement.
