(A possible world in which some life-saving agency prefers to save 901 able-bodied people and allows 1000 disabled people to die might also might include significant consequences
You didn’t really propose the counterfactual. But beyond that, the essence of my metric is that a world which adds 2 years to the lives of 1000 triple amputees compared to a world which regenerates the limbs of 500 of those triple amputees, but fails to extend their lifespans by two years. I don’t pretend to know at exactly what numbers preference becomes confusing for most people, but I know for darn sure that most people will risk death in operations to improve or preserve their functioning. How do you include that fact in a metric other than by showing a positive value for positive outcomes?

By extrapolating from the choices of the people involved? It seems to me that people with no legs have just as much interest in staying alive as people with two legs. That doesn’t mean they have an interest in staying no-legged rather than becoming two-legged; but I don’t consider “give Bob his legs back” equivalent to “kill Bob and save Alice, who has legs”, either.
