Without some serious marketing dollars behind a new storefront, I don't think it would make a serious dent the market share of the existing stores, and therefore wouldn't really represent any significant increase in sales for publishers.
(...and to head off the obvious counter-argument-- I don't think that "association with ENWorld" meets the level of marketing weight I'm talking about -- I mean ad pushes into other geek media, an effort to bring brick-and-mortar retail aboard, etc.)
Without attracting a new audience segment, all you're doing is cutting a miniscule slice off the same pie, and I'm sorry -- but there is such a thing as diminishing returns.
