Hi Scott,
I love flying off the snow! It's at least as easy as land based flying and often easier. I haven't noticed any handling strangeness beyond maybe a need for a couple of clicks of elevator trim.
The skis glide so freely the airplane quickly picks up speed, then you can run across the snow as fast as you like before smoothly lifting off. Landings can be made "hot" or slow. A low idle setting is important, particularly on hard snow. The cooler air provides more power and better lift. I think the skis can also provide lift with some positive incidence because my planes fly really slow in the winter! My favorite condition is a smooth, firm base with 1-2 inches of powder on top. It's great to to do touch-n-go, leaving 10 foot long tracks!
pointers:
1. Aluminum skis get icy unless you can keep them in the shade or in the snow. Covering the bottoms with plastic tape really helps.
2. The skis usually lower the nose a bit so check your prop clearance.
3. A steerable tailwheel has always worked fine for me, others build little tailskis.
4. Don't bother with deep powder unless you can plow or pack it down.
So my answer is, get some Dubro plastic skis and do it
