IIRC, in the FFSG announcement about the French team for Worlds some of the skaters were mentioned as going to the Universiade - I think it was Gwendolyn Didier and one of the younger dance teams, I forgot which one.
Czisny won the U.S. Collegiate Championship in August to qualify for this event, and the men's winner was Jason Wong. If Jason doesn't go, the next in line is Jonathan Cassar, who made such an impression on the audience at U.S. Nationals last week.
Actually, the timing is not too bad for Alissa if she wants to do that much skating. Four Continents, Feb. 2-8; Universiade, Feb. 18-28 (I don't know when the figure skating will be); then Worlds, March 22-29.
