If you're asking whether Asada would also have talent as a pairs skater, I'd agree with you that it would be interesting to see. Two other equally charming, musical skaters, Naomi Nari Nam and Yuka Sato, have done wonderful work in "second careers" as pairs skaters--Nam as an eligible skater, Sato as a professional. I'm sure Asada could do the same. She'd bring an added asset to the pair: up till now, no male pairs skater could do a triple axel and expect his partner to mirror him. Mao Asada's partner wouldn't have such a limitation!
Additionally, many singles skaters have skated with a partner for a one-time-only performance. One memorable pairing from the past (available on YouTube), from the late seventies or early eighties, is a duet featuring John Curry and Peggy Fleming. Another is a lovely exhibition by Paul Wylie and Nancy Kerrigan for (I think) the 1992 Olympics, to music from Miss Saigon. I'm sure the rest of you can think of others.
