Here's the thing: this is a D&D community. You posted here because others told you your game was "5E-lite", and myself and others are explaining it really isn't. I don't know who told you it was...
I don't think you can try to take the "best from here and there", toss it together, and try to make something "coherent". But the other issue is no one agrees which things are the best. You say there are "superior mechanics", but that is completely subjective.
For example, I am a fan of using a Wound system of some sort, as you do, but I know the vast majority of D&D players don't--it adds an extra level of complexity, even if it is a defining way. Which is one of the reasons why your claim this was 5E-lite had me interested---I want a 5E-lite, which was what my friends and I were doing, but of course our game has grown into a life of its own, which seems like yours did.
Now, I read your other posts. I get what you are trying to do--I'm just not certain making a piecemeal game leads to goo design in general.
Finally, I am very serious about game design and I know our other DM who used to post here on EnWorld is even more into it than I am, so you can expect criticism if that is what you asked for, but you aren't going to just get a bunch of fluff and hype to make you feel good about what you've made. I think a lot of it has merit, but I know it wasn't what I expected nor what I am personally looking for in a new game.
So, I hope you understand I am taking my free time to reply, hoping it will help or perhaps give you some perspective. Most people here will help. I know it is difficult to not become defensive about your own creation, but understand you put it out here for criticism and suggestions, and that is what you are getting (from myself, anyway.... I haven't had time to read the other posts).
