Honestly, I've been rooting for a prequel ever since the first movie came out. I would be thrilled if something like that were to happen, but I have to say I would rather they cast younger actors for it. I love Michael Douglas, but this seems complicated for nothing to go to the lengths of digitally de-aging him for an entire movie (except for when he'd be in the suit of course).
But it would be so awesome to see him invent the suit, meeting Jan, working with Peggy and Howard Stark, etc... So much potential!
