Neat, but this looks equivalent to Harsanyi to me.

Harsanyi's theorem concerns a "social welfare function" that society is supposed to maximize. The present theorem makes no such assumption.

I didn't notice until reading your comment that your theorem gives an answer to the question of why the aggregation should be VNM-rational.
