Thank you for an interesting and informative exposition. I’ve always been struck by the similarities, as practical morality, between the teachings of Jesus (as given in the Gospels, not institutions or self-proclaimed ‘Christians’) and those of the Buddha.

As for a transformative ethic that is ‘of this world’, there is one at hand: real justice. The ethic of real justice involves mutual respect. All of the elements of real justice — its determiners and its referents, as a philosopher should say — are contained within material existence. Applying real justice to society would maximize liberty, reinforce political democracy, and transform the socio-economic outcomes of the existing (monetary) economy, to include increasing sustainability (even without more regulations).

A five-minute summary of real justice is available here on Medium in “Real Justice (summarized for a ‘5 min read’).”
