Here is how I look at it.
My friend and I both like cereal but we both like different kinds. I like Froot Loops and my friend likes Apple Jacks. Well the problem is there is only one bowl and we both want what we like now. Well a third person comes up with the idea of mixing the two cereals together so we can both have what we like. Well the problem with that is I don't like Apple Jacks and he doesn't like Froot Loops and the cereal is already mixed. Neither one of us want to have to pick out which cereal we like out of the bowl.
So why would a person who isn't a fan of 4th edition want to play a game that contains elements of 4th edition in it?
This analogy is so far from my experience of the game, that it suggests you have not sincerely attempted to play the game as written, but are looking for things not to like.

Also if you don't like optional rules then 5e probably isn't for you.
I still think there would be a way to capture the D&D feel while creating a whole new game.
