Why couldn't for example, a Reading train leaving Waterloo specify
that only the doors of the first 8 carriages will open at certain
stations and the rear 8 carriages at the others?

At that, why could two stops at certain stations not be planned, with
the first 8 carriages, then another brief halt for the rear 8 carriages?

Both ideas need to consider the huge operational problems of the Windsor
lines through Barnes and Richmond - successive level crossings in an
urban area, stations abutting those crossings, Barnes station abutting
the Hounslow loop junction, frequent local stoppers to fit between the
fast services.
