Of course - it will mean lot of work/time spent on such secondary function instead of concentrating on main things like getting most optimum runners configuration for most performance gains, and given often insufficient available man-hours to dedicate for that one often needs to prioritise which matters most, but theoretically one should be able to customize second sensor placement even without making header 100% replica of stock construction-wise, if decided to concentrate on that.

Nope. I suggest you read up on how the ECU determines if the cat is functional, and how it uses the signals from the two O2 sensors to determine if a CEL is in order.
Your post conclusively tells me that you have ZERO clue as to how the system operates, and are purely speculating as to how you *think* it works (hint: that's not how it works).
