I go over that in my video about what defines CoH as a game and it specifies why I love the balance and rng simulator that is CoH. For those interested it is here:

Suffice it to say that without rng CoH 2 would be just another WW2 RTS. Your idea is horrible in my opinion and would encourage more rage than the current system, it would confuse new players and increase the skill ceiling needed to master the game as well as confuse intermediate players who may mistaking think that after a miss the next shot is a guaranteed hit. Further more the game is BALANCED on rng, to do what you suggest would throw the games balance into disarray even more than it is now and would essentially kill the game.
TL;DR All in all your idea is conceptually flaw because it raises the skill ceiling of the game and will throw the balance of the game into disarray.
