If I were you, I wouldn't buy Ambassador until after staying the 10 nights and after your status has updated to 12/31/23. If your promo Diamond expires on, e.g., March 19, 2023, I doubt the extension trick will work, but that's just a guess.
When the Straight to Diamond promo was active and public, didn't it work like this?
1. Enroll in promo
2. Immediately buy amb (don't need to stay any nights)
3. Diamond extended to Dec 2023
In that case my line of thinking is
1. Enroll in promo
2. Buy amb in 2023, which
should extend it into 2024.
