I wonder if it might be possible to remove the residual valve from one of the ports and run discs with the earlier cylinder.

Did the same thing years ago. Sorry no part number, but do know I found a manual Disc/drum MC that worked very well for many decades. As I recall only modification was possibly to the push rod length. I also used an adjustable proportioning valve. As I recall I left my arms and just changed stuff from ball joints out ( was on a 66 ).
I was lucky to have a parts store that knew how to read a parts book. My advice is to find such a store and give them ALL your business, so they can stay around. Online and chain stores are cheap, but you get what you pay for.
Sorry to go off on a rant there, but bottom line it can be done. I also prefer manual brakes. Good luck on your project, Tom
