Yeah, that's what I think I'm going to do. Scuff the epoxy, then filler, then epoxy.

A friend of mine who does body work, suggested epoxy only. Epoxy over bare metal, filler, then again with epoxy. Biggest point he made was to make sure the metal was warm so condensation wouldn't get trapped between the primer and filler or the bare metal and filler
I think people are pretty consistent with no filler over etch since the acid is the issue. Condensation looks like a bit of a confound so I'm glad I did epoxy first.
