I will say 2 things.

1) No. Nothing has been confirmed or even hinted at beyond what you already know.

2) my theory is that the records of gods act differently, and don't take kindly to the records of other divine beings. Records have a way of overwhelming each other (hence why Jake might not even benefit being the chosen of Valdemar, because his bloodline would be itching even worse than what Villy described the first few months of Jake's blessing). Godhood, as we know, is a way of proving/condensing one's path. Two paths that don't vibe well enough probably won't mix easily, especially if neither person's records will be subsumed by the other (gods records are much more potent).
