You may have missed my point. You don't need to borrow stuff from Pod::Coverage::Moose, because Pod::Coverage::Moose already seems to support Moo classes and roles.
Just use Pod::Coverage::Moose as-is, but put the tests in your xt directory instead of t. That way, MakeMaker (or whatever you're using to package your distribution) should find and run the test while it's building the distribution tarball, but the test will not automatically run on end users' systems.
