Ok.

I had something similar in mind, but slightly different.

emacs-async package explicitly transfers pre-defined set of variables to
the async Emacs process and cannot transfer non-printable variables
(like markers or buffers).

But may it be possible to

1. Limit the async process memory to a small lexical subset of symbols
   (within a function).

2. Every time the async process needs to read/write a symbol slot
   outside its lexical scope, query the main Emacs process.

More concretely, is it possible to copy internal Elisp object
representations between Emacs processes and arrange mutability to query
the right Emacs process that "owns" the object?

The inter-process communication does not have to be asynchronous, but
may work similar to the existing thread implementation.
