I am sure you are aware, but there are emerging projects like gleam in the beam world. There was also caramel. I don’t know if compiling to beam interests you.
(Also, as a former akka and Haskell production dev, and current elixir/elm dev, I would personally focus on building out ihp or servant ecosystems further for boring crud apps and then let that naturally drive people calling for a beam like framework for the minority that want to reach for such scalability or availability, after building out a basic web application that gets millions of users)
