Perhaps you should read your own posts, or better explain what you mean? You said that with a loadout change the plane would be renamed Bf.109G-10 when you land and that different skins would have to be available, NOT that it's performance would change in any way.
If you are suggesting that engine performance, drastic weight differences, and skin selections would change with the loadout choice, why would HTC just not add the Bf.109G10 as a separate aircraft?
