Those are some really good suggestions, but I feel that, for the majority of them, I won't attempt to implement them until the remake reaches the same point as the original. I've put them in a txt document for later, for now, I'll quickly go over my ideas on some of them.
School Visitors:
Mom/sis: Pick up from school early, probably during lunchtime. Can be picked up by Mom, Sis or both, which would lead to normal scenes or threesomes between family members and/or teachers.
Nurse Donna: Mandatory Health Checkup. Could implement all of her hospital scenes.
As for the rest of the main characters. A potential excuse is that Mom asked them to pick him up from school, maybe a forged note? Could even implement a bit of NTR, with Pito or Thomas acting upset and/or confused when Lisa or Sarah pick up Peter
More Overworld Meeting
I don't have any concrete ideas for where I'll implement them, but I'll make sure I do.
Sydney Wake Up
There are already several scenes that could work with this idea, so I'll try and implement it.
As for the rest, I'll leave them till the remake is almost done or up-to-date
