I was emailing with the guy who did it a few years back. And he said he didn't get any help from PACE. He did the wine tweaks on his own.

Do this as a test. Load 16 instances of Kontakt on 16 tracks in Reaper with no instruments loaded. On my system (Manjaro/KDE) with latest Wine Staging, each instance of Kontakt takes up 250MB when looking at system memory usage. So it does not seem to be sharing memory. On Windows, the first instance of Kontakt will take 250MB and then every other instance of Kontakt takes a very small amount of memory.

Next test, load two instances of Kontakt, each with the same instrument. In Windows, only the first instrument instance is loaded into memory. The second duplicate instrument shares memory with the first and doesn't add to the memory usage. In Linux/Wine, they each take up the same amount of memory - so double the memory usage. Again, indicating that memory is not being shared in Wine.

I'm very sorry if I'm not understanding here, but shouldn't the shared memory per VST instance be MUCH higher for instruments like Kontakt? 5MB won't even load the blank plugin with no samples loaded. Having only 5MB of shared memory for multiple Kontakt instances or Omnispheres etc. doesn't seem like it would be of any help at all.
