Erlang VM is built on the premise that it runs a functional language. I would argue that it will be extremely inefficient to implement non-function language to run on Erlang VM. By non-functional I mean language that is based on mutable and shared state. You can look at Elixir (http://elixir-lang.org/) to see great example of an alternative language that runs natively on Erlang VM. While offering syntax that is more familiar to many people Elixir retains all basic restrictions of Erlang.
