No amount of modifications you can do will change the amount of load that axle can carry.

It's possible. Our trailer is currently in storage so I don't have access to my certification label. My guess is that it's the same 4000# axle but since it was built/sold before the fall of 2017, it didn't follow the (yet to be established) 10% reserve. The 2040# tires they fitted at the time would have been a 2% reserve and a poster child for why the RVIA took action. The link to the 2017 1750RD that you provided may have been built later in 2017 or retrofitted to the 2200# tires by the dealer to meet the 10% reserve. Hard to tell.
As I said earlier, I have absolutely no intention of overloading the 4000# axle. I just need some margin other than what the factory fitted 2040# tires provided when they were stamped, probably some time in 2016. If I understand correctly, even if I had switched to RVIA recommended 2200# tires a year ago, and given up to 10% degradation per year, they would have been back down to a marginal 2000# capacity already this spring.
That was kind of why I was looking at 2800# tires in the first place, so I can get about four seasons out of them before they degrade into 2000# tires. That, and reading multiple recommendations to go from a D to an E load range when replacing tires, for margin, not increased payload. My main question was related to rim selection and the implications of going from a 14" to a 15" rim while retaining the original five-hole pattern.
