Would it be possible in the current state?
The MMC5 expansion chip is pretty much 99% similar to the 2A03 (but with only the pulse channels)
so I'm wondering if it'd just be possible to log VGMs from that by making it a "dual NES APU" kind of deal...

In theory, it's possible. But as far as I know we don't have any way to log MMC5 registers like this at the moment.

There are some minor differences compared with the 2A03 APU, the most important one in this case is that the length counter is twice as fast on the MMC5 compared with the 2A03 APU. This means that songs that use the MMC5 length counter (in a meaningful way) could sound incorrect when played back with NES APU.
