I want to see if this is possible.
Uh... no...! These chips provide extra audio, and are not by any means compatible with the NES CPU. And like I just said, the 2A03 is the CPU, it's responsible for executing the programs, if you get rid of it your NES is dead.
Yes, you can, but it'd be like replacing your PC's processor chip with a sound card's sound chip.
Here's how the NES is put together:
A single integrated circuit ("chip") can have multiple logic blocks on it. In the NES, the 2A03 chip contains a 6502-compatible CPU block, a sound block, and a simple fixed-function DMA ("direct memory access") block that helped move data. The 2C02 chip contains the PPU (Picture Processing Unit), a custom video interface controller designed by Ricoh.
It would be unwise to replace a chip that has both a CPU and sound with a chip that has only sound.

You were great. My congrats.
Well, the custom sound chips are a replace or enhancement for the 2a03 through the audio pin. Your point is interesting, but meaningless over the hardware view. Perhaps wasting a few hundred of hours modifying an emulator to do such thing...
but the japanese guys did something different - they replaced the square synthesis with sound samples.
