Yes, but there is not full overlap of the capabilities. Fusion doesn't seem to provide a way to define a class with access control, base classes, and member functions as a sequence. I'm assuming BOOST_FUSION_DEFINE_STRUCT has no runtime overhead, although I could not find and explicit statement to that effect.
If you put all the members that should participate in the comparison into the fusion sequence, you can then wrap this sequence in another class with base classes and other methods. Depending on requirements, the fusion sequence could either be another base class, or it could be a member of the wrapper class with the wrapper class defining delegating operators for the comparisons.
