As you already found inside the documentation, creating remote root containers to a windows host is not currently supported and is not planned for the G.A. release.
You can still install manually the FuseESB/FuseMQ etc distribution to the remote windows host and join the cluster using the fabric:join command.
Regarding your second question, using a unix emulator could possibly get you further, but its not a recommendation.
Thanks a lot for the feedback about the bouncycastle jce provider.
