No, most heal sluts are bad because they don't engage early on - making it far less likely for Jhin to secure kills early on. IMO the only ones that work well for him are Nami and Rakan because they're actually aggressive with stuns WHILE providing him with shields and/or heals.
Jhin is essentially an early & mid game ADC now, and has been for a while. He isn't late game because he can't take down tanks and will likely get caught off easily by an enemy assassin or diver during a team fight.
When playing Jhin, your goal is to win your lane and secure as many kills as possible so that you become overfed. You use this early/mid game advantage to out-gold the enemy team. You have to end games before the 35-minute mark or he'll become useless - ESPECIALLY SO if the enemy team has more than two tanky champions.
