It seems like this could plausibly have interesting consequences for dealing with (moral) normative uncertainty - it might make the whole process a fair bit easier if we could consequentialise all moral theories as a starting point (there would still be work to do but it seems like a good start...)
This was demonstrated, in a certain limited way, in Peterson (2009). See also Lowry & Peterson (2011).
The Peterson result provides an "asymmetry argument" in favor of consequentialism:
Another argument in favor of consequentialism has to do with the causes of different types of moral judgments: see Are Deontological Moral Judgments Rationalizations?
Update: see Carl's criticism.
