Looking good, thx.
I don't think you need to do the convoluted call from one script to another, just extract the required method so that it can be called from either.
Then, in the wrapper, you can actually use JBang's //SOURCE annotation to create the dependency and import for the other class.
You can find an example of this at:
https://github.com/marcnuri-demo/blog-tutorials/blob/11ac44f167581f07e11d49d7e0192dfcbee71915/java-virtual-threads-project-loom-complete-guide/Test.java#L4-L9

Also, I'm not sure if we should add a Makefile target for this, the Makefile could easily check too if JBang is available and spit an error in case it isn't.
