And if there were something like this in other headers that retains the

I don’t think this is quite right—I think the Reply-To needs to include all of
the senders or else every reply will be an off-list reply (would cut down on
noise, admittedly). Otherwise this would be a great solution. But because
of the way it interacts with MUAs, I do not think it would work in a way that
doesn’t violate the principle of least surprise.
