I've been wondering if you could compute the interference pattern and then compute the view from any specific angle - possibly on a GPU. A sort of 2d way to save a 3d model.

Also wondering how feasible it is to "reproject" a hologram from one plane to another - rendering multiple "objects" into one hologram/interference pattern.

This is definitely possible and is the basis for some computational holography.

And a holographic interference pattern is definitely a way to store a 3D image in a 2D plane, and I think a part of what won the Nobel prize in physics when holography was invented.

And also the subject of the ideas like the holographic universe.
