The result would be similar to what the tag list looks like with your new feature. But rather than making it up by definition, my suggestion is to create it dynamically when quering data.
Ok, now I understand what you mean. This is a kind-of related tags explorer, right? A virtual tree where you can navigate tag relations, where notes themselves define these relations.
I have two ideas how to implement this:
1) Extensions for the search box. After a tag is entered, Ctrl+Space suggests only tags related to the current tag selection AND to the tags entered into the field.
2) Maybe Tag Selection bar could also help here. It will allow to easily add related tags to the selection.
The problem is that this info is not readily available, CN will have to do some undercover queries to get this information. I'm not sure this is worth the trouble. In any case, I'd prefer a double number display, smth like 
for quick editing without the use of the mouse, when you need to edit several notes, e.g. after importing data. Yes, hide the source-field. No need for it at the moment.
