Nothing here's is strictly impossible - you can always create a simulated HW
model in SW, and have a one-to-one mapping with the HW entities.
But "unreasonable amount of code" comes very close to it.

Nope, I don't mind doing the work. What I would appreciate is some
constructive suggestions on a seemingly feasible approach that might work.
I feel like I've been bashed enough for one day. :-)
