With the CID the way it is I'd drop the templars for two units of bastions and then laugh as they get to defensive strike and then if they die make another attach thanks to the VoJ. And if they don't kill them they all go back up to full on your turn.
I don't know, but with how small your list is and how much work your jacks and Vessels have to pull here, I'm not sure I like your list. It feels very bloated on the support side of things. I feel you don't have enough models to benefit from the Vessel's abilities either. Maybe drop an Indictor for 2 Dervish? Maybe squeeze a Repenter in some how to get some more anti-troop coverage?
Piggy Backing off what eggory has to say, I would definitely look at a version of this in the Exemplar theme. All that healing paired with Sanguine Bond just seems too silly not to try out.
