Data that might be useful: The MSP430 MCU with the smallest RAM that also has ROM beyond the 64 kB boundary is the msp430fr5969. It has 2 kB RAM, and 16KB in far memory. It's the only one with 2 kB; every other MCU for which 20-bit addresses might actually be useful has at least 4 kB RAM. These aren't the value-line chips where everybody has to worry about running out of stack space.
I'm gonna need to see evidence that using two words to store callee-saved registers is a serious problem before taking the risk of introducing bugs by making the ABI more complicated in an attempt to avoid doing so.
