Considering that when we see the dancestors they have the same aspect as the main trolls, I think it's fair to say that Vrissy's aspect will still be Light.

I think, to reflect that she is in many ways a less selfish version of Vriska, that she shares the spotlight she steals with others, it would be cool with she was a Rogue of Light.

I'm not really too sure on the others, but I think Yiffy will probably be a time player, given her personality of acting first which is pretty typical of time players, and I'm pretty drawn to Tavvy as a Rage player, as a reflection of both Gamzee and Jake.
