Combine Custom Operators with scripting

I am building an extension where I scripted several super operators, I noticed Custom Operators Extension can turn a process into a custom operator. I want to turn my super operator in the way Custom Operators Extension did into operators with the inner structure, is there any way I can define the inner structure of a super operator when scripting so that it's no longer empty when used? Or, is there any way that I can use Custom Operators Extension to create an extension that consists of some super operators created by Custom Operators Extension while having some of the elementary operators defined by myself in Java?

Best,
