The Atom and The Wasp in "Inch-High Insurgency!"

Evangeline Lilly has been cast as the female lead in the Ant-Man movie, but her exact role has not been announced yet.  I would have to believe she is playing Janet Van Dyne, but with the strange timeline of the movie that is not a certainty.  Paul Rudd is starring as Scott Lang, while Michael Douglas will appear as Hank Pym.  Given Douglas' age, I am guessing that if he is even shown as Ant-Man at all, it will be during flashbacks - and I don't know what that means for Jan.  If Lilly is indeed starring as the to-be Wasp, It seems like her back story will be quite a bit altered from the comics.
