I think a plausible win condition is that society has some level moral concern for all sentient beings (it doesn’t necessarily need to be entirely suffering-focused) as well as stable mechanisms to implement positive-sum cooperation or compromise. The latter guarantees that moral concerns are taken into account and possible gains from trade can be achieved. (An example for this could be cultivated meat, which allows us to reduce animal suffering while accommodating the interests of meat eaters.)
However, I think suffering reducers in particular should perhaps not focus on imagining best-case outcomes. It is plausible (though not obvious) that we should focus on preventing worst-case outcomes rather than shooting for utopian outcomes, as the difference in expected suffering between a worst-case and the median outcome may be much greater than the difference between the median outcome and the best possible future.
