Alias spin-off with Sloane, Sark and Peyton?

When ABC decided that this was going to be the last season of Alias, J.J. Abrams wasn't in on the discussions. It wasn't until after the decision was made that Abrams was called while filming Mission Impossible 3 in China. While he's not all that surprised at the decision, he is saddened to see it end . . . make that "somewhat" end. Abrams has been discussing the possibility of doing something (spin-off? TV movie?) involving the characters Sark (David Anders), Peyton (Amy Acker) and Sloane (Ron Rifkin). Y'know, I might be OK with that idea, but only if they do something fresh with it; the whole Alias vibe to me is stale.
