I think a `configure-runtime` submodule (in the expansion of any module using the language) is the right place for this kind of configuration.
The `configure-runtime` submodule is similar to `main`, it that it is only used when the enclosing module is the main module of a program. Instead of a direct `(current-readtable ...)`, I think you'll want a direct `(current-prompt-read ...)`, where the prompt read handler uses `(parameterize ([current-readtable ...]) (read-syntax ...))`.
