Insomniac's Spider-Man X Gravity Rush
Kat's and Peter's personality and terrible luck seem like their would mesh well together, and the Gravity Queen's movement mechanics are very similar to and every bit as fun as Spider-Man's. I'd love to see a GR sequel with the tighter controls and minimap/compass of SM, and a cel-shaded SM sequel with sidequests as weird as GR's could get.
Plus the opportunity to see a GR-style combination finisher where Kat's using Lunar Style to Wormhole Kick all over the boss while Pete's going full on Maximum Spider on their opponent, then ending with her switching to Jupiter Style and charging up a Surge Kick, which is in turn ampilfied by Spider-Man landing a full out ground pound and then using webbing and Spider-Strength to launch her down even harder would be super cool, as would having Pete be her mentor in being a Friendly Neighborhood Super Hero and intrepid photographer while having to crash at her surprisingly cozy sewer when he inevitably gets evicted again.
