James Deen fucked man butts professionally at one point?
Not that I know of, although I must confess I don't stay on top of the man-butts-getting-fucked genre of adult video. But your question has prompted a sudden awareness: The "crossover work" reference here may be a reference to gay-straight crossover, rather than adult-mainstream crossover as I inferred. If so, that may not point toward James Deen. Honestly I didn't think it was him anyway; I simply thought the reporter confused James Deen with Xander Corvus based on physical similarity.
Has Xander Corvus done gay-for-pay adult video work, or is he gay or bisexual?
