This is less of a problem in a finite series like Kamen Rider, I admit.
Yeah, I think most of the issues you cited could probably be dealt with fairly reasonably in a series that was promised not to run longer than 50 episodes, assuming it was made one of the major themes of the show and they stuck with it. You can come up with plots for that amount of run-time; you just have to be careful with it and not overplay your hand.
Brave of Legend Da Garn and GEAR Fighter Dendoh are both fun mecha series that show school-age kids trying to balance crime-fighting secret identities with school/family responsibilities. Some of the episodes are about that conflict, others just use it for situational comedy, and some just don't make it an issue at all. After all, it would be sort of contrived if there was always a recital or a baseball game or a work deadline when the monster stuff was going down...
