The SNES architecture looks pretty similar to the NES architecture in a lot of ways. It might have been possible to make it work, if it was a design goal. The PPUs are similar, the CPU has a compatability mode for the NES CPU, the controller bus is the same with a different connector. Sega does what Nintendon't, and their 16-bit system was backwards compatible with (one of their) 8-bit systems, if you got the adapter that adapts the slot and includes a boot rom. Apple also did it; the 16-bit Apple IIgs used more or less the same CPU as the SNES, and used the CPU compat mode to run regular Apple II software. Sega
