There are too many assumptions with this theory, with the merging theory, you only have to make one assumption: fusion, and it answers all those questions above. No, it's not an assumtion, but already a fact. Itachi literally said that Madara became a new wielder of Izuna's eyes. Since the previous panels depicted Madara takind out Izuna's eyes (which didn't happen that way, but doesn't really matter in this case), it's kinda clear how they were passed. Thanks to the interaction between the new eyes and the new owner, it became a new doujutsu (EMS), with the light never fading away and the abilities getting stronger. It was the main explanation of the EMS made by Itachi, and there's no more info in the series which can explain it better. And you're speculating on the whole "merging process" that never took place or wasn't ever mentioned in the fisrt place, despite us receving a lot of info about genetic experiments in the series. Besides, by your logic, you have to make the assumptions how the merging of two pairs of blind/half-blind eyes should help in restoring the eyesight.
