Could Amumu be a half Yordle?

One aspect of Amumu's lore is that noone really knows if he was a Yordle or just a child.

He also has an unexplained curse.

Is it possible that the confusion and curse are caused by the fact that he is both? And optimistic half yordle half human child cursed for his own existence as an anomaly in this world, which he has no control over?

I think it could be a viable explanation and that it could allow Riot to explore Yordle and human relationships a bit more, while satisfying both those who want Amumu to be a human child and those who want him as a Yordle.

It was also make his identity very unique, and fit with Shurima's obvious Egyptian inspiration by having a demi-spirit as their emperor.
