Youtube Link: Reharmonisation Techniques

I've been browsing youtube and have found a handful of videos that have helped me write more rules.

This one in particular mentions dominant seventh chords replacing other dominant seventh chords, while going on to talk about how dominant seventh chords can replace target chords that would otherwise resolve a line.

A couple of rules found here include:

-REPLACE MINOR SEVENTH CHORD WITH A DIMINISHED SEVENTH CHORD A MINOR THIRD BELOW
-REPLACE A TARGET RESOLVING CHORD WITH A DOMINANT SEVENTH CHORD A FIFTH UP

There are more rules that can be found within this video (in the video the presenter creates rules that he uses himself), and they'll be introduced later on as I develop the ruleset.
