Although it started as a joke in an Ed Greenwood chat at Gencon a few years ago, I would pay good money for a "Ladies of the 'Realms" Swimsuit calendar. Imagine tastefully done prints by Larry Elmore of the seven sisters, of Catti-brie, Alusair Nacacia, etc. (though not necessarily scantily clad!),
"Men of the Realms" could include Wulfgar, Fzoul Chembryl, etc. Not recycled artwork, mind you - but single protraits for each such character.
Perhaps even do it as a "flip-side" publication, in a similar manner to Dungeon/Polyhedron.
