Sure, but that's a significant amount of work; AIUI macOS/amd64 works pretty much out of the box with minimal tweaks to DSMOS. If it uses cryptographic protections (say, decrypting the kernel) added to T2 firmware, this becomes a lot more of a hassle to build a macOS distribution that runs without a T2.
In any case, this is a polar bear on an iceberg: in a relatively short while, Apple won't be shipping anything intel, and a few years after that macOS will be ARM-only.
