All mpl sequences can be used in fusion. An mpl::set_c or vector_c, or even
range_c are all usable in fusion. Just include the necessary files
<boost/fusion/sequence/adapted/mpl.hpp> and you're done.

If you want it converted, you simply write:

     fusion::set<...> fs = ms;

where fs is your fusion set and ms is your mpl set. Here's an example
(untested):

     typedef mpl::set_c<int,1,2,3> ms_type;
     fusion::result_of::as_set<ms_type>::type fs_type;
     fs_type fs = ms_type();
