Other than that, and since you ask - In my view there's never anything "fatal" about mixing, it either works or it doesn't.
Just don't get too caught up by the illusions of numbers (you listed a good deal of digits in your outline). Your ear is your friend, your eyes not so much wink
And lastly, I had never heard of these plugins you mentioned, so now this information highway we got here has become a two-way street, the best kind there is! Thank you smile

Just because you can, doesn't mean you should!
