What you are doing is unsupported, could and would break suddenly with no warning whatsoever.
You are relying on package protected functionality of a Codename One class, this is an implementation detail that might change.
I suggest you create a new question discussing why you chose to do this change in the first place. I'm assuming its a struggle with layout managers.

As to your question: You can subclass components in the GUI builder by overriding createComponent including for Form.

Serves me right contradicting an advice from Chen ;-)

You can use my suggestion to override createComponent.
