I remember skimming an article by a female philosopher that argued that each of the three major kinds of ethics can actually be expressed in terms of each other.
There is an article by Marcia Baron in which she rejects the view that 'consequentialism, virtue ethics, and Kantian ethics form three distinct and competing ethical theories'. While this does not imply that they are mutually reducible, it goes a long way to reconciling them. I am naturally unable to say whether this is the article to which you refer but it seems acutely relevant to your concerns. Baron's position is reinforced by Philip Pettit in 'Rival Theories?'. See M. Baron et al., Three Methods of Ethics, Oxford : Blackwell, 1997. The quote appears in Baron's essay on p.4; for Pettit's contribution see pp. 252-6.
