Aside from the hanger, there should be some right/left symmetry, so if the left has some kind of inserts on both sides, then the right probably did too.
I'd probably use the skewer to clamp, and epoxy that washer into place, and try it out.
Probably not a life and death risk. So, if the wheel pops out, and rubs the chainstays???
The issue would be whether or not I'd be comfortable taking it on a multi-day trip. I'd probably prefer taking it a few days around the neighborhood, but part of the decision will depend on how isolated one will be, and how harmful a day or so of downtime could be.
Be aware that frame mods might affect any warranty coverage, if that is an issue.
