I've heard of folks mixing powdered metal & mica powders with laquer (good ol' Carol Duvall again), but never ep. EP is really ultra fine bits of plastic that melt at a fairly low temp, not a true enamel. I'd be worried that something hot getting set down or near whatever had the mixed laquer on it would have it's finish ruined by the melted ep. That's said, it might work for decorative purposes.
