It won't work: they are completely different physically (pin count: 22 vs 24) & in functionality (the 64 phonemes are in a different order, and don't map 1:1).
NB. In AppleWin I used the SSI263's phonemes for SC01 emulation, but this is clearly only a rough approximation (but good enough for the 2 games that use the SC01!).
