It's probably feasible to do plug-in and/or pack for any change mgmt app, but this is not on the roadmap at this time. I don't see docs for ChangeMan ZMF online, so I can't assess the technical feasibility, implementation approach or effort. Note that Serena is a competitor, so I don't think they'd be receptive to partner. The best approach would be for a motivated RA customer to use the RDK to build some CLI or REST actions, depending on the available API's, and contribute that pack to the community.
