I applaud your efforts here, but what would -really- be a nice build would be a similar module which would emulate the signal from the post-cat oxygen sensor.

Thus allowing us to use aftermarket non-cat headers without the lack of a cat triggering the CEL due to the improper signal from the secondary oxygen sensor.

How complicated would this sort of thingy be to construct?
