The approach you describe above (a process buffer with a filter) would
be one viable approach, perhaps even something as simple as using
`async-shell-command' would be workable. One place to start looking
would be in ob-eval.el for external evaluation and ob-comint for session
based evaluation.
The trick would be in setting up the post-execution code block handling
(namely results parsing and insertion) to run after external evaluation
has completed.
If anyone wants to look into the code and write/propose a way forward
I'm happy to help in any way I can.
Cheers,
