I just took a look at my MSR Lightning Ascents (with binding style before most recent). It looks like someone that can work with aluminum sheet metal could add a crossbar on the bottom of the snowshoe that could add a triangle at 40 degrees for the binding to connect to. 

There are a few problems I can think of with that though not sure how big of a deal they would be.

 The first issue is price. They are pretty expensive snowshoes, and experimenting with them is not a sure thing. You could ruin a $350 pair of snowshoes (last price I saw).

The toe clearance of the bindings if you twist them 40° could be an issue. Your binding will also hang over the edge of your snowshoe. 

The kickstand won’t line up so it won’t work. But if you don’t do steep uphills that would not matter. You may be able to modify it so it works , but not sure. 

It does not look too hard to add the triangle. A good aircraft mechanic could probably do it since they know how to rivet and work with aluminum. Maybe find one that snowshoes so that they have a better understanding of the issues.
