Hi Francis, There is an older paper that mentions this idea: Tsao et al, Acta Cryst B48 (1992), 75-88. However, when you look at the paper, small-angle scattering data is not the only thing that was used. In particular, if my memory serves me right, the 60-fold averaging applied to the problem really made all the difference in getting the phases right. The big difference that works to your advantage is that small-angle scattering was not nearly as well developed at the time as it is now. For example, I don't think they could get molecular envelopes in 1992. There is sufficient information available these days that the test could be done (for appropriate systems).
