But … given Einstein is a REx that emulates all the peripherals of an MP2K, we have it as an example of a “HAL” that could serve as a template for adapting vanilla NewtonOS to a new platform (such as a Raspberry Pi or similar).

IIUC, this was the original purpose of the REx.

So … using a well-documented/understood target, it’d be approximately a similar order of magnitude of work to writing Einstein, with the bonus of having Einstein as an example, and the penalty of dealing with real hardware not virtual.

Or am I misunderstanding something?
