Although I would prefer Bruce Banner (Hulk) I understand that this would have, euh, unwanted implications depending on which version we'd have. I definitely wouldn't mind a professor Hulk (during the Pantheon saga) or when he was Jarella's husband and K'ai's king.
So if that wouldn't be an option, I would opt for Henry Pym (Ant-Man, Giant-Man, Goliath, Yellowjacket) and Janet van Dyne (Wasp) or just Henry Pym (Wasp).
