That is certainly feasible. There is enough GPIO off the PI to allow it to be extended to support scanning the keyboard and writing to a display.
It would be an interesting project, but an orphan. You would be writing every line of code to support the display and keyboard, then it wouldn't run TRS-80 software unless you wrote a simulator for it. Boot times would not be as fast as a M100, and you would have to be careful about backing up the SD card, as losing power could corrupt it. An interesting, long term project, but I am not sure of its use case.
