No (, at least I don't see how) ... you'd expect the valid functions to
be the operations sensible on sequences A&B both.  With this in
mind (sequences not variadics), it would be more reasonable to propose
the following methinks:

  fusion::inner_product<SequenceA, SequenceB, FunctionSequence>
{ /*,,,*/ }
