It’s a shame it won’t make a close pass, that would be amazing!

Probably no way it could unexpectedly become naked eye brightness, too far away. They can go the other way though. Remember Comet Ison in 2013? It was said it could become magnitude -11.6, nearly as bright as the full moon. Went around the Sun and disappeared. Could not be seen by the naked eye after perihelion.
I have seen Ikeya-Seki, 1965, magnitude -10; Halley, 1986, +2, Hale Bopp, 1995, -1.0. We are about due for another good one.

Wiki shows perihelion at ~ 11AU, outside the orbit of Saturn. Thus, it will only get less than 2 mag. brighter.
