It’s certainly possible. How easy or hard it will be will depend a lot on the quality of your model. 3d scans often result in iffy geometry in terms of having zillions of polygons, awkward triangulation, reversed normals, etc., etc.
There are a few ways you would approach it, or you could use a combination of:
*parametric deformers, such as the bulge, taper, and bend deformers;
*keyframed point-level animation (PLA);
*morphing (requires Mocca or a plugin).
As far as modeling the PLA/morph targets, I would use a lot of the Mesh Brush and the Magnet Tool.
