Man. This would be perfect with integration of rules, pathauto, because then it would be really great for tags because I could set patterns.
I don't understand what you want to do with Rules and Pathauto.
TVI replaces taxonomy term pages with Views and support inheritance for hierarchical terms.
So using pathauto by default you can choose to build path for your tags and TVI will just show the selected View on the aliased page.
Could you explain me your problem a bit more ?
Not sure what the problem is here either.
