Not sure that will swing it, have a look at https://github.com/JohnEarnest/Mako/tree/master Which is basically a Forth for games, that runs on the JVM, and in the browser.

The issue as I see it, is that you have to have a model of the datastack in your head at all times. That's fine for your own code, but for other people's code, stack diagrams will only take you so far.

The ability to scan code, rather than reading it, allow you to mentally drill down when you are ready. Forth requires immersion.

Something like https://xorvoid.com/forsp.html I'm guessing is really the bridge. Something that allows variables without being too complex.
