I've been tinkering with this approach and it fills the need pretty well. I hadn't really thought of using title lists in fields before, so using that + the list macro + transclusion has helped a great deal.
The only thing that has felt a little awkward has been having to create strings of tiddlers connected by fields to model some of the more sophisticated relationships. Thanks for the pointers!
