Mary-Kate and Ashley Olsen (search) want to make Cole and Dylan Sprouse (search) the male versions of their teenage girl merchandising empire, The Wall Street Journal reported.

"My sister and I started the whole 'tween empire," Ashley Olsen was quoted as saying. "I definitely see the potential for the boys to do that sort of thing."

The 13-year-old Sprouse twins shared the role of Julian in Adam Sandler's 1999 film, "Big Daddy" (search), just as the entrepreneurial 19-year-old twin actresses played Michelle Tanner on television's "Full House" (search), which aired from 1987-1995.

With the brand name of D.C. Sprouse, Cole and Dylan will be the face of a boys division that will include DVD movies, CDs and other merchandise for the Olsens' Dualstar Entertainment Group, the newspaper reported Monday.

"They love to Rollerblade, they like to surf, skate and are into videogames. ... They love animals," said the Sprouses' manager, Josh Werkman. "They're boy boys in every sense of the term."

Home video sales and product sponsorships ranging from a fashion line to toothpaste have made the "Mary-Kate and Ashley" brand a billion-dollar enterprise. Each twin is estimated to be worth more than $150 million.

The Olsens, now college students, starred in 2004's "New York Minute."
