Sorry, but no.. That does not seem like a good approach at all. First Cordova should release their yearly new Cordova-Android version, then you should update to the new Cordova-Android and raise the target SDK.
Cordova-Android |
Target API |
11.X.X |
SDK 31 |
10.X.X |
SDK 30 |
9.X.X |
SDK 29 |
Cordova-Android 11 is not released yet. I think you should wait and raise the target SDK after cordova officially supports it.
Not even all of your own official plugins officially supports SDK31
