I don’t know offhand of any quantitative estimates but “moral enhancement” is a potentially relevant area of study. For example:
Moral neuroenhancement
Modeling the social dynamics of moral enhancement: Social strategies sold over the counter and the stability of society
Should we select for genetic moral enhancement? A thought experiment using the MoralKinder (MK+) haplotype
