Dave, In some ways I am already doing what you ask but the details are deep within greater solutions. For example my MyMenus plugin (not developed beyond when I released it) at http://tiddlywiki.psat.com.au/mymenus/, has menu items defined in fields that can be any form of wiki text including macros and transclusions. The macro that displays the menu then "transcludes" the value in each field, which the wikification process returns the "computed value", if the menu is used on a particular tiddler it references value on the current tiddler.
Similarly in my edit-fields macros (not published) I have a tiddler that defines each field name (field definition tiddler), when viewing a tiddler, the view template will transclude the field definition tiddler to display the contents of the current tiddlers field(s). More importantly it uses some gymnastics to allow the editing of that field in the current tiddler, using the field definition. So for example if I have a project field, it will lookup all tiddlers tagged project (which are in the current "domain" eg work) from which I can set the current project. Everything is possible.
