"it's not a big snow year and the weather is so warm right now it seems like a good year to try."
Interesting idea. If the weather remains stable it would be feasible, but keep in mind it's still winter and things can change fast; You are definitely well back in the interior, so GPS plus either PLB or sat phone would be prudent in case things go south. Escape routes preplanned with GPS coordinates marked also advisable, along with a couple days extra food in case you have to go to ground. Avalanches would be a major hazard if you got a heavy dump 2-3 days in. 7 days might be optimistic if you encounter extensive icy conditions. Lots to think about.
