But the burning question is could you fiddle with the extension rom code and use it as a
loadable device driver? After all you could transfer rom BASIC to a disk file and run it
that way.

Why can't you just write a small batch

room on a 360K, then you can use a second floppy. We used to do this for
customers all the time, 15 years ago. Also included small start up menus,
etc.
The "driver" is a ROM. You'd have to start by writing a LOADABLE driver.
It would be convenient to have another machine on hand while writing it,
since the "driver" is to get the video to work.
It would be MUCH MUCH easier to install a CGA or MDA card, and contact
Cindy Croxton in Texas and buy one of her "9-pin monitors".
