Unfortunately no, those machines came out well before the 32k CMOS static RAM, so they sort of invented their own pinout for the little 8k modules.
Same with the ROM on the earlier M100's which also had a non-standard pinout.

If you wanted a project, you could probably replace the entire 32k RAM with a single chip, but it would require quite a lot of white-wires, trace cutting and some external decoder logic.
