Also, even though I'd have some doubts about a gay man playing a character so tied to an opposite sex love interest, NPH proved that he could pull it off with HIMYM. Also, Dougie Houser + Dr. Horrible as Hank Pym is awesome casting. That combined with the upcoming finale of HIMYM means he'll have more availability. So please Marvel, do it because it would be awesome casting.
Also, knowing Edgar Wright, he'd probably use NPH's singing talents in one scene or another. Imainge Ant-Man seranading MODOK to confuse him, then following up with a retort along the lines of, "Your foolish attempts to confuse me were in vein. Although amusing, you must still be exterminated."
