... Why?
Quinn as a top laner is widely disliked, both by top lane players and Quinn mains. Quinn top only exists to shut down melee laners, and has absolutely no lategame effectiveness, whether you build full assassin or bruiser.
Quinn has never seen significant play in the jungle and reworking her or buffing her to make her a jungler would not only be a lot of pointless work but would also likely be both startling to her playerbase and annoying to all other players (quite like Jungle Nidalee, but Nid has thematic reasons to be there)
Quinn's ideal lane/role is as an Assassin in either bot or mid. She currently functions in that role quite well. She certainly does need some changes right now, but she doesn't need anything that would change her lane/role identity.
