The other reason Planet Hulk wouldn't work at this point is because if you look at the tone and themes of the Marvel movies thus far, if Hulk did become a menace to humanity and kill a lot of innocents, the first thing to come into the characters' minds is not going to be 'oh let's exile Hulk into space that we only just figured out is populated.' It would be a far more organic fit for them to build a conflict around the characters taking opposing stances as to whether or not to kill the Hulk, recognizing that Banner is not in control of himself and a victim of the Hulk in his own way, and others prioritizing the needs of the many over the needs of their friend. Similarly, the first real look we're going to have at cosmic Marvel is Guardians of the Galaxy. Despite the odd assortment of creatures we've already seen in the trailer, we've also seen that there are a lot of humans out there in space, they're creating a very 'human relate-able' feel to cosmic Marvel, and we're supposed to feel like the 12 billion innocents Glenn Close is talking about needing the Guardians to protect are people we can feel for and relate to and actually worry about what happens to them. Then jumping from that feel of 'space people are people to' and building an entire premise around 'Hulk is a threat to innocent life, so let's exile him to space despite all the other innocent life out there he can rampage through' - it doesn't work. The natural conflict around a homicidal Hulk, in THIS incarnation of the Marvel U is whether or not to eliminate the threat for good, not turn him into a John Carter of Mars character type.
