I used to do this for a living.

Professional photographers do something like what you describe using a setup like this:

It is pretty easy to build something like this at home. A little experimentation will show you what the challenges are. Notice that the device does not have a fixed frame. Every paper printout has its own details of margins, sizes etc. Every shot has to be adjusted to fit the frame of your camera. The lighting has to be controlled so that you get the same shade of white from various qualities of papers. It can be quite demanding.

After you have fooled around with this for a while, you may conclude that scanning is actually pretty quick.
