That was one example in a very large space of possibilities; you can differentiate the consequences of actions in any way you please, as long as you’re doing so in a well-behaved way. You don’t even need to be using a sum—average utilitarianism doesn’t.
This does carry a couple of caveats, of course. Some methods give much less pathological results than others, and some are much less well studied.
Summing over actual violated boundaries is also a possible consequentialism, but it does not seem to capture the intuitions of those deontological theories which disallow you to push the fat guy. Suppose the driver of the trolley is a mustache-twirling villain who has tied the other five people to the tracks deliberately to run the trolley over them (thus violating their boundaries). Deontologists would say this makes little difference for your choice in the dilemma, you are still not permitted to throw the fat man on the tracks to save them. This deontological rule cannot be mimicked with a consequentialism that assigns high negative value to boundary-violations regardless of agent. It can, perhaps, (I am not entirely sure) be mimicked with a consequentialism that assigns high negative value to the subjective feeling of violating a boundary yourself.
So you’re willing to allow summing over feelings of violated boundaries, but not summing over actual violated boundaries, interesting.
