Your roof braces looks similar to some we have and they have certainly also taken lots of snow for years. I wasn't worried about the construction, just mentioning asymmetric unloading as that can be an unexpected challenge. I have to admit as a Norwegian that snowshoes are next to a total mystery when ski exists. We do have them, but I can only remember seeing them used in very tight bushy woods.
Skis are great for someone moving, but for someone who makes frequent stops and wants to do things other than move forward, skis are just not as effective.
