Default OBDII, Piggyback, and having fun with EGO

So here's the plan. 99 BEGi S4. Xede piggy/interceptor and stock PCM. Car must pass OBDII emissions once per year.

Parts to be aquired:
3" Enthuza exhaust, no cat in midpipe.
Innovate LC1

Program LC1 output 1 to offset stoich to 15.7 and run to PCM primary o2 input. Car will run a little lean in closed loop but stock PCM will be none the wiser.
Program LC1 output 2 to offset stoich to 16.0 and run to PCM secondary o2 input. Car will run without cat, but the PCM's cat efficiency monitor will have no idea.

Will need to either leave stock narrowband sensors bundled under the car or figure out what resistors will be required to eliminate heater open CELs.

Will also require retaining a 2nd LC1 to integrate into Xede.

Thoughts?
