What kinds of documents do you mean?
There is the BEAM book and also BEAM wisdom. Perhaps you can find even more valuable resources in Best resources on BEAM internals?.
As well as there might be some wisdom available in the OTP sourcecode or in the two RUST re-implementations ErlangRT and enigma.
You could, but if your language has a lot of mutability or objects (I do infer this from your constant mention of the JVM) or other semantics building on those, then the BEAM is probably not a suitable runtime for your language.
Still, building a compiler for your language on the BEAM is a valid choice.
