That is not going to work. You will change back pressure which will make sure the sensors throw your car in an error.
Also a sport car DP will not fit in the space next to the engine I heard (not 100% sure), so those are not an option, next to the fact that you put too much strain on the OPFs.
You can change whatever you want, but it are the sensors at the end of the downpipes that are the issue not the OPF itself. The trick is to fool the car the sensors are reading the right back pressure or make sure that what they read is not taken in consideration by the ECU.
If you have created that set up you can what you want. Emission testing is not applicable now. Your MOT is three years away.
