Maybe void fusions/trace rifles slow (not suppress)? Maybe solar fusions/TR burn? And arc fusions/TR electrify? My first thought was this was going to be too much but maybe if the effect applied to a shield break on TRs and automatically on fusions to keep from abusing them? I don't think a kinectic version of these guns should be possible, but an added effect on them would be nice. Arguably all energy weapons should have some sort of effect imo but if any weapon types deserves it it'd be ones with no kinetic counterpart
