Hammock in a snow cave...?

[job13_5]

Can it be done? Can you set up a hammock inside a snow cave?

I don't know anything about snow, really, or snow anchors, so I'm not sure if this is possible. But I've attached a picture of an initial thought. I figured that if there's enough snow b/w the outside anchor and the inside hammock attachment point, there'd be a potential for it to sustain the pull. What do you think? Is it ignorant to think that if you can stand on top of a snow cave w/o it caving in, you should be able to setup a hammock inside it?

I have an outdoor living skills class that I'm taking this winter and I'd love to give it a whirl during one of our outings.
