3D scanner => LEGO brick printer

I have to search more, but imagine combining a 3D scanning app like:
   Autodesk 123D - 123D Catch turn photos into 3D models
with a LEGO printer that prints in LEGO bricks, like this one:

The connection could be done via something like this (free) editor:

Anybody up to test this (crazy) idea?! :D
