Fan Casting Ant-Man and the Wasp

Hank Pym and Janet Van Dyne has just become famous after inventing what's known as the Pym Particle, a way for humans to change their size to be as big as an ant (which they've managed to make through expiriments on Janet's mutant DNA). However, one day their sample for the Pym Particle is stolen and is starting to get sold to HYDRA, which infuriates Hank and Janet and make them create their alter-egos named Ant-Man and the Wasp using the few remains of the sample.
