Why not ditch the buses and just start everyone around the same time? In Australia, all levels are starting around 8:45am (3-18yo). There's a bit of flexibility in that a school yard is monitored a bit earlier, or the first session is free play ("Investigation") which allows children to be dropped off sequentially if parents are handling that. Ends up being a window of about 8:35-8:55 so my school run can get two both schools in time.
There is affordable and easy to book out of school hours care for anything earlier or later.
Outside of formal lessons, I'd fill gaps with investigative play, extracurricular at-school sport, or casual activities to line up various year levels.
