Maybe they could try a Maestro alt-universe time traveling plotline? That'd be neat: Juxtapose the monstrous nature of Maestro with Banner's more subdued mastery?
If you want a “greatest hits” for Hulk, check out: Planet Hulk, World War Hulk, Immortal Hulk, maybe Infernal Hulk for more modern, and check out any Hulk comics with Paul Jenkins’ name on the cover. Beyond that, it’s just up to your taste.
