Probably not, because the limiting factor on train throughput is remaining a safe braking distance behind the train in front. If the train in front of you has stopped at station D then you need to stop in station C even if you don't open the doors.
(You could get around that by running the trains further apart, but that would be a critical loss of capacity).
Right but the Victoria line puts a lot of effort into keeping station stop time to a minimum for the sake of capacity (it's the most intensive metro line in London, at 36-37tph, and one of the most intensive in the world). One way or another you have to space the trains out more to do skip-stopping.
