Almost any character(s) in Unicode "can be" used with almost any other. You can surround U+2044 with emoji if you like. That doesn't mean you should. This is a key point. You can use many code points to get some "effect", but that doesn't mean it represents good practice or should be recommended. There are no "traffic cops" out there that will flag you down for having made a poor decision, but that's not a reason enough to endorse random suggestions. This goes particularly for practices that need support in systems and/or fonts to work correctly. If some implementer supports the recommended normal size digits for 2044 why should they do the additional work of making sure it works for super/sub script. A./
