Jay...why not carry out your plan EXACTLY as you define and see how easy it is for you. Don't change the rules or make excuses half way through. Plan to do this for a month or so and then reassess then.
If you can't do it then restart and try again. If you fail again then maybe its time to admit that the addiction may be stronger than you think and as strong as you fear and then you can have a different type of conversation.
the reason I say this is that my consumption was broadly level to yours for years and at around this kind of level I started to do what you are doing.....making all sorts of rules to convince myself that alcohol could continue to be a part of my life and that I could cut down.
Turns out that was my AV talking and I was stupid enough to listen to it. I then wasted 10 more years and paid all sorts of prices. Hopefully your path is not similar, that was just my experience. Your can be very different.
