The CamptoCamp.org website has a search by date and area function which is useful for seeing what people have done at the same time in previous years, here is 2010 for the Ecrins
as Ken says not a lot of non-glacial skiing on that list and here for the Cerces
that said, the C2C folks are not that active in the area. You can do the same kind of search with skitour
You should be able to ski stuff from Bonnenuit - North face of the Galibier, Eveches, Cerces, Galibier (if the tunnel / pass is open by the time you travel). Stuff from the Lauteret may also be possible, the Combneynots, maybe Mt Chaberton near to Montgenevre (get in there quick, they are building ski lifts all over it soon). Col d’Izoard maybe
There has been quite a lot of snow recently. You can still tour in low lying ranges such as the Chartreuse but it is getting much warmer again, there is a foehn wind of a force I’ve rarely seen blowing so expect the snow line to move up to the 1800m mark quite rapidly.
