In light of sunsetting i think this would be the best move for bungie, as this would pay respect to the time investment players put into them. Players who unlocked the pinnicel version could then have the exotic version auto unlocked. Making these weapons into exotic would also cut down on their usage as it would take up the exotic slot and force players to make choises; I.E. do i want to run breakneck for add clear or xenophage for boss dps. Pre-nerfed break neck, lunas/NF, and recluse were already boarder line exotics so it would add a few new exotics to the collections without taking away content.
