I'm looking for these very same features to begin a project with multiple sites. I began building it myself, but found that WP had virtually the same thing I was building already in the Jetpack plugin.

We would be interested in paying a good developer to port these features to C5, and would allow you to keep the rights to the code to package for your own sales.

Let me know if there is any interest in helping.

Thanks
