Even if you give components the same name, for the engine they’re not the same components, so if you truly want to move them to c++, you’ll have to manually setup them in children and instances again.
As a workaround, you can get references to the components in c++ by component tags or otherwise, and then work with them in code.
I personally would love to see something similar to "meta = (BindWidget)" but for blueprints.
