It seems to me that you would have no way of setting the MTU on the inner tunnel. That's true - other than inefficient packet fragmentation, is there anything else that would be an issue? > Is there a reason why you can't try multiple interfaces? I cannot bring up more than a single interface on Android. I am not sure about interface management on Windows with wg.exe, but wireguard.exe certainly does not permit multiple interfaces to be brought up.
