My reason for wanting to eliminate the FV (IF i went that route), would be to do a "clean" removal rather than have stuff such as the 02 sensor sitting there unplugged.
For instance, say on a chevy some people just remove the AIR pump's belt. I would go all the way and remove the pump, control system and exchange the exhaust manifolds for ones without AIR tube holes JUST to make it a sanitary change with no remnants left as eye sores.

As it has become evident that removing the FV properly would require backdating the entire CIS, that is what i would do if so inclined to eliminate the lambda system.
Do it ALL or not at all mentality.

Don't get the wrong impression, i might just as well be inclined to restore the lambda system to 100% correct and functional operation.
For now, the car really likes the 02 sensor unplugged. Give the motor what it wants !
