Looking forward to seeing what you do with this...
I've been planning to start a thread on my TRS80 project, but have been spending too much time trying to get the disk-controller emulator working.
Just for grins, here are a few shots of where mine's at...
First version of the PCB needs a few extra pullups:

It's able to read and write from "cassette":

And plays all of the games I've tried on it. Here's Star Trek ala 1979...

Have been working on the disk emulator for far too long now...

But even though it's still very flaky (I'm getting more read failures than from a real floppy

), it will boot (and somewhat run) LDOS:

Definitely looking forward to your approach.
