I agree that your restatement is internally consistent.

I don't see how such a theory would really be "sensible," in terms of being helpful during moral dilemmas. If it turns out that moral intuitions are totally inconsistent, doesn't "think it over and then trust your gut" give the same recommendations, fit the profile of being deontological, and have the advantage of being easy to remember?

I guess if you were interested in a purely descriptive theory of morality I could conceive of this being the best way to handle things for a long time, but it still flies in the face of the idea that morality was shaped by economic pressures and should therefore have an economic shape, which I find lots of support for, so my upvote remains with my credence being maybe .5%-1%, I think about 2 decibels lower than yours.
