A mirrored push is basically:

  - push all refs, i.e., a "+refs/*:refs/*" refspec

  - enable --prune, to delete any branches that don't exist on the local
    side

But you can do those two things separately if you like. So your options are either:

  1. Drop the pruning (in which case deleted branches from the sync may
     accumulate, but depending on the patterns that may or may not be a
     problem).

  2. Use two different namespaces for the synced branches and the
     private ones (e.g., refs/mirror/* in addition to your branches in
     refs/heads/*). The obvious downside is that anybody cloning your
     downstream mirror doesn't pick up refs/mirror unless they configure
     that refspec explicitly.
