You're pretty much describing the way Apache ACE handles the deployment of bundles (and configuration).
They are distributed in a deployment package. Deployment packages are versioned sets of artifacts.
Every time you change something in the set of bundles (for that client) its version number
is bumped.

The management agent on the client can make that decision (to go back to any previous version
in fact). Hooking that up to the UI isn't hard.
