Advanced membrane use case: Transformations between data models?

This project has largely been about mirroring and distortions of object graphs. But what if we took it one step further (or several)?

I can imagine three object graphs:
- Abstract syntax tree
- Intermediate object model ("structures" in ts-morph parlance) for users to work with
- Code generation

This is clearly in pipe dream territory right now. But if the middle layer was the non-proxy layer, it could be beautiful.
