Well they still reference that Brother Blood now so i don't think they can retcon him, but they can possibly retcon Arrow - Vengeance. After all, they retconned parts of it for Slade's backstory in Season 6. So Trigon could be changed. However i couldn't see him being a villain on Arrow unless they massively underpower him.
