I really want to wish you luck in your goal.

Its simple math:
Before tonsillectomy: 95th percentile was consistently in the 14s to 15s
After tonsillectomy full recovery: 95th percentile dropped into the low to mid 11s
If I go off all klonopin (a potent depressant and sedative), my experience has been a point drop for each mg of klonopin. Im on four mg klonopin, therefore I should expect a drop of three to four points, which would bring me down to low 8s or the 7s. Lets be conservative and say, the low 8s after discontinuing ALL klonopin.
Then lose forty pounds and get down to 200 lbs again. Im down to the low 7s now.
Then have deviated nasal septum corrective surgery and sinus surgery to reduce NAR. I figure another drop of a point. Down to low 6s
Then I have bariatric surgery and lose the remaining fat and get down to 165, my ideal weight. That drops my pressure needs down to under 4.

I am a skeptic by nature, but its simple math, really.
I don't want to burst your bubble of optimism, but I have to address your misuse of "simple mathematics".
Pugsy tried to point this out to you earlier. What your data
definitively shows is that with less tissue and less weight and fewer drugs, it requires
less air pressure to keep your airway from collapsing. In other words, it's now easier to prevent your airway from collapsing. That does not imply your airway will no longer collapse when there is NO extra air pressure to splint it open.
To put it bluntly:
A reduction in the pressure to keep your airway open does NOT mean that your untreated OSA has gotten any better. It may have gotten better. Or it may be about the same. Or it may actually have gotten worse. We just don't know, and the kind of pressure data is not enough to draw any legitimate conclusion about what's going on with your
untreated OSA.
The only way to tell whether your
untreated OSA has actually changed at all is to undergo another sleep study without a CPAP. It could be that even though it is easier to prop the airway open now, in its natural (CPAP-less) state, your airway is still prone to collapsing just as often as it did before you started CPAP. Or it could very be that with less tonsil and throat tissue and with less drugs in your system, you airway actually does collapse less often during the night in its natural (CPAP-less) state.
So even if in the long run you succeed in getting your pressure needs all the way down to the 4--6cm range, the real question will be:
How often does your airway collapse when there is NO CPAP pressure? And if you are lucky and you succeed in all your plans, the real question will still be:
Can you get the number of airway collapses down to less than 5 per hour when you are NOT using CPAP?
Having said all that, I want to add this: You plan on losing a significant amount of weight and intend to keep it off. You've had one surgical change in the structure of the upper airway and tentatively plan on some nose surgery that could (marginally) help the airway a bit more. You're tapering off of a medicine with some known potent side effects when it comes to night time breathing. Add all that up, and it's reasonable to think that once you've lost all the weight and you've tapered the klonopin as far as you intend to taper it, that it is very reasonable to request another diagnostic sleep study be done to find out just what the heck your upper airway actually does do when you're sleeping without a CPAP. And that would be true
even if you didn't see any further reduction in the pressure needs between now and the time you finish your weight loss project and the klonopin tapering. In other words:
If you get down to your goal of 165 lbs and manage to keep the weight there for several months, it's well worth requesting a new sleep study regardless of whether your pressure needs have continued to drop as you think they will or not.
And having said all that: There's the final usual caveat---if you do cure your OSA through substantial weight loss, the tonsellectomy and nose surgery, and the klonopin taper,
you'll have to keep the weight off forever. Because if you gain the weight back, then chances are the OSA will come back, perhaps with a vengeance.
Best of luck
