Not yet. We have most of a working implementation, but HepMC itself
doesn't yet provide a functional weight container (I'm working on fixing
it for a patch release) and as far as I know no (?) shower generators
are currently propagating the weights through to the HepMC output.

Incidentally, how would you like to have the weights represented in the
output? We have a plan, but I'm interested to know what people expect!
