After a quick look at their web site, I would suggest that they would get better noise and durability results by using a secondary PCB and socket for routing signals than by using wires. The design would no longer be parfocal with a non-modified camera, but that would be a mostly moot point.
For a practical comparison of the output, I'd also like to see the raw data stretched to the same level as the modified camera, to compare noise levels.
