No, the mirthful messiahs are Caliborn and Calliope. That's why he raised Calliope just the same and never gave Caliborn any advantages. He's even shown to like the Callie baby more than the Cal baby.

When it comes to raising babies you’d prefer a calm baby to one that’s always scratching and biting. But here’s something from an archive of Hussie’s old deleted tumblr saying that Doc Scratch and LE are the messiahs:

“LE has always been around influencing troll culture from the start, and it seems he was always the embodiment of the mirthful messiahs the highbloods worshiped, since he was really two beings, Doc Scratch and LE, both “mirthful” puppet-based entities, in their own ways. Gamzee’s honking, the humorous brutality of the subjugglators and their dark spiritual beliefs, all could be traced to LE.“
