I was trying to make a DPS Justicar in the soul planner, but it occurred to me that the soul doesn't have much synergy with the Cleric's (other) DPS-focused souls because Salvation and Reparation have their healing effects cut by half for other souls' abilities.

Despite that, would a Justicar/Inquisitor or Justicar/Cabalist meant for DPSing and offhealing via the damage be a viable build, or would the healing from the Justicar tree be negligible?

I'm thinking that maybe a Cabalist/Justicar/??? could be a powerful character to reckon with. Cabalist would use AoE to deal lots of damage total, translating to lots of healing total (for himself and his allies).
