Judging by the example of Babashka, Graal apparently does give you a "huge opaque runtime", and also there seem to be severe limitations on loading code. I think it basically has to include all the Clojure code up front, which makes it arguably NOT interactive. RPython and PyPy are great engineering and great projects, but I think RPython has not quite "escaped" into the real of general purpose language implementation - https://www.pypy.org/posts/2018/09/the-first-15-years-of-pypy-3412615975376972020.html https://www.pypy.org/posts/2018/09/the-first-15-years-of-pyp... I think it taught a lot of valuable lessons in this space, but it's not really an answer to the stated problem.
