The lack of DQ boys in general is saddening, considering it's been how many decades of cute boys. I dunno about "Smash content" specifically, but if you're interested in the protags like I am, for as little as there is, there's a fair amount of yaoi for The Luminary (DQ XI Hero) and Roto (DQ III Hero).
God I wish there was more of Six and Eight though, they're hotties imo. Seven and The Celestial (DQ IX Hero) are cute too. Frankly I would bone all of them.
