Kind of a flexfuel stage2

Lately I was thinking of creating Kind of flexfuel for EA888 gen 1&2 with Oem K03 turbo. This would be for my VW T6 TSI.
My point is not so much to gain power but here in France were E85 is half the price of 93 is to run cheaper. And that than take in between 15L/KM to 20L/KM

If i install LNF injector's 0261500055 that deliver 18% more without rescaling injector in the ecu fuel map then my car on 93 gazoline will adjust LTFT by removing 18%.
My ECU will still have the range to add 25% so if you add this to those 18%
that let the ECU be able to add 43% of fuel by tricking it. So plenty enough for E85.

So then on the fueling side with O2 sensor runing in closed loop and adapting the LTFT it should be OK togged the right AF on any E85 mix from 0 to 100%?
Or do you think I missed something their?

Then with a REVO stage 2 and their SPS+ I could tweak the 100 octane file to run at max timing and max boost ( position 9) to get a bit more power on E85 than on 93 gazoline.

Do you think I'm stupide or it could work?

PS: I had something similar in My VW R32 flexfuel tune with the injector scaled lower than what they are.
