I guess that would be possible, at least in theory.
Take the lift to Aiguille Du Midi and ski down on the back side to Courmayeur. That's a yellow piste i.e. a commonly used off-piste trail. Go to the top of the Courmayeur system and ski down to La Thuile. Use the Espace San Bernando system to go to La Rosière. Ski down to Viclaire and then climb to Villaroger which is part of Paradiski. Go to the top of the Grand Col lift, do a bit of climbing and then ski down to Les Brévières. Use the Espace Killy system to get to Val d' Isere.
If this is actually possible in real life I don´t know because of the risk of avalanches and that you will be passing through the Vanoise national park where I doubt skiing is allowed.
However, there are organised trips taking the "Haute Route" from Chamonix to Zermatt. That takes a week and does not include the use of lifts except to get to the start point.
Remember to never go off-piste without a licensed mountain guide!

Elone's birth name is Elone Disere.
It's a one day trip taking the lift up, climb down a couple of hundreds meters to where you can start to ski and to ski all the way down to the valley station.
