Coney, anyone? ;p
Seriously, though, just about
any spell/ritual/charm can be transferred/converted into TRoS. It's just a matter of determining the desired effects and matching them to the possible Vagaries. I have already done this with several, in fact.
I would, however, be careful keeping them linked to their old dice pool system. True, WW and TRoS both rely on dice pools, but they are not all that similar. Both in feel, and in play.
