I don't think so. I think the theory put forth earlier in the thread that Jake is a subpersonality of Steven is correct. They could not balance the heart while Steven and Marc went through their history, but as soon as Steven fell into the sand leaving Marc behind, the heart balanced. If it was imbalanced due to Jake being locked away, Marc wouldn't have balanced after Steven fell.Looking back at it, Taweret only had Marc's and Steven's hearts and tried to balance them. Jake (and presumably his heart) was still locked away in the sarcophagus.
