Hello, and welcome back!
These are some interesting requests that I guess we all would like to see in the future. In such cases, the Features IFC Category may be your best friend. There, you can find most of the requests you asked on this topic and you can vote for them, or (once reaching TL2) create them yourself if there isn’t one. After a quick research, I was able to find some of the requests/ideas you asked for, such as smoother A/P, clearance delivery frequency, A330-200, etc.
Regarding this, I believe it goes against the feature request rules as it is a special livery.
I’m sure most (if not all) of the features you asked for will come eventually. Just be patient for the time being and enjoy the current features, aircraft and airports we already have :)
Thanks, and have a good day!
