>>Would it be possible to listen to gweths while on the trails?

Technically possible, but not likely. Given how trails and gweths work, it'd require an elaborate workaround to get it right. The trail rewrite does not address the issues that make compatibility between these systems troublesome, since those issues are in the core assumptions about how trails function.
