First is seeing how viable the x-ray for all scenes is. Very short answer with limited time put in on it is, maybe, but unlikely.
WatsonTouya, who drew the artwork and put together the animations for the x-ray used in Ballfondlers, did a bit of looking into it, and there are several big issues.
The first being that the art is for a night time shot, so the images have a blue-ish tinge over them, minor and fixable, but also means new artwork.
Second is the direction of the artwork. While we can easily move the image around the screen, the thrust direction is upwards, which won't match all animations, making it look bizarre if Morty is thrusting in a different direction.
Lastly, and a much larger issue, is frame rate. The x-rays were made to run at 7 frames a second, while most animations in the game are either 24 or 30. Even syncing up the the key frame timing, the different frame speeds look odd together. There may be a way to do it (I could, for example, make in-betweens, or use ATL to add animations, and fill in the "missing" frames), but it is a much bigger project than I had hoped it would be.
