dark preformance psudo divided mani

From reading about the divided set ups it seems that the connected wastegate ports more or less defeats the purpose of separating the exhaust pulses from each other. My plan:
Cut off the exhaust tube
cap off the hole in the flanged side
Add a flange on the non flanged side and use it to cap it off with another vband flange, cya in case one 45mm gate isn't enough.

This separates the exhaust pulses and basically puts the holset back to where it was from the factory, waste gate off of one half of the manifold, but with a much bigger waste gate. The turbo going on is a hx40 in a 17cm divided t4 housing.

Why am I putting the effort in on this manifold, Simple I have it and it was cheap.

My question, I dont know enough about flow to know if I am going to have boost creep. The car has plenty of fuel to support 30+ lbs of boost (mod list not updated)
I dont know may other types of cars that require dual waste gates other than just for balance. Is my thought process on this flawed? Am I wasting my time? all thoughts are appreciated

The thought is to keep the flow through all the cylinders as even as possible. By wastegating 2 cylinders, you'll flow more though those cylinders than you will through the ones powering the turbo. You'll be lean in 2 cylinders, and rich in the others.

Some people have added a divider down the center of the wastegate tube. Then the exhaust pulses are divided all the way up to the wastegate plunger. At that point, the turbo is spooled and you're no longer worried with keeping them as separated as possible.

the divider was my initial thought on solving the problem, after looking in to it and trying to get a machine shop to contour the end of the divider to the profile of the valve on the waste gate I decided to pass on that one. If that pair of cyl are running lean they should have an egt a little bit hotter than the other side right? I was thinking about that before hand and put in a spot for two egt's so I can see what happening. all thats left before I find out what this does it to build or buy an 02 housing. I will update when I get results.
