Such a concept is not possible politically. Pu239 breeding is not acceptable both to the government of the US and the current head of the NRC. The thorium based U232/U233 fuel cycle produced by a fusion/fission hybrid may be acceptable as proliferation resistant because of the high level of U232 that is generated by fusion.
High U232 content in U233 provides 6 barriers to proliferation, compared to none for Pu239. George Miley is a supporter of the fusion/fission hybrid. Hans A. Bathe was the originator of the idea http://www.marcobresci.it/docs/fusione_ibrida.pdf Fusion bred U233 has a very high U232 content due to the 2n and 3n reaction. This provides U233 with 6 barriers to proliferation, compared to none for Pu239. U233 can also be denatured with U238. This mix is also proliferation resistant.
