This would make typeid polymorphic in other words a template.

Wrong. parts of typeid can be read by ctfe.

Perhaps but I don't see how to do that without introducing
polymorphic types (meaning template types)

Wrong. The polymorphic nature you need to get back to the type
would be a massive change.
