Couldn't this be done with union directories with the proper ordering and use '-c'?
This thread from 24 years ago might be relevant. The goal was to stash files that had been pulled from the remote fs, to handle low bandwidth and unreliable networks. If I understand your use case, you want to be able to keep the changes on the local shadow fs until ready to push them to the remote? https://9fans.topicbox.com/groups/9fans/T74b794a0b25b3452-M4e93273ae029a34387d5b847/9fans-persistent-cache-for-cfs I think for environments where the external source (fs) is heavily used, inconsistency would become an issue.
