Hi Alan,
The indieweb bouncing around can be a bit confusing.
I was thinking of a sort of SPLOT tool for a multisite that you might be interested in.

Basically a button you could add to a post that would allow viewers to clone that post to their own site.( It sounds like Tom has a good starter).

It could be used by a teacher to give a template to a pupil which they would then edit.

A wee bit of blue sky on a holiday.
