There's nothing stopping you from using lisp as a transpiler to generate the java, or different interop glue for the lowest common factor code everyone will surely understand.

The magic was always that it was always an AST all the way down, and you can create and experiment with your own personal semantics and vocabulary, so long as the language is expressive enough to define them in the domain specific way you are doing development. For example a language that is aware of what libraries and databases you're tying together and abstracts the way they interconnect, can compose multiple libraries together without the kludgy plumbing, or autogenerates boilerplate along the way that's required by your build and tests. As long as you generate readable clean Java or whatever, your coworkers won't care how you got there
