What I envision would work to create a near perfect .stl replication every time for every material.

Z axis resolution better than .1mm. X-Y resolution depending on desired speed. Scan area defined by the printer its attached to.

Complex shapes will require more than 1 scan which will be stitched together.

The short answer is yes but the longer answer needs a lot more info.
