I am going to be honest, I know very little about this comics series but some of the pictures I found of some of the mainstream Marvel characters looked very cool.
Thor is a Blob Thor, not too much to change really. Trimmed his helmet, ground away some of his face and beard. Green Stuff to make the new mouth and tentacles, more for the forearm coverings. The left arm, in the pictures I found, seemed like it was covered with chain mail but the right was bare. I used a technique I've tried once before to create the chainmail effect, heating a leather punch tool and branding his arm. I could not find a decent hammer in the fodder bin so the hammer is actually from a key chain. The cape is a modified Odin cape.
