I'd rather his arc just be having to adjust to being back home with everyone else.
But that only means something if there's a major time jump. Season three has a short one of three months (?), but in order for Hopper to need any personal period of adjustment, I would say a time jump of a few years needs to happen, so by that time, Joyce and Eleven have more or less moved on with their lives, which would be a challenge for Hopper.
