You could take some inspiration from the suggestion topic maybe.

F-22 would be at higher BR than the F-35A/B/C because of overall better performance.
Also the stealth bombers in no way they would be at rank X, especially for air battles, they would be at a huge lower BR, kinda like the F-117 treatment.
Daily reminder that a new Polish tech tree suggestion is currently in development
Next Gen aircraft, Next Gen US Mains incoming, its going to get spicy once every f22 fanboy sees that they can buy one in WT to mog on everyone else (assumption) then looks inside: wtf is a meteor?!
The tsunami of US mains flooding the forum to cry will have absolutely no precedent coming close in the entire history of the game
The highest US premiums will also hit record sales and their br bracket will be seriously ruined for a while
