I don't think he will. For one, the dialogue that he needed to eat her was a mistake made in the chapter version and it has since been corrected in the published volume. The correct text states that Historia would need to be a Titan in order for Eren to use the power of the Founding Titan.

I'm pretty sure that Ymir would not be happy with that and she'd slug Eren good.
