No shit use https://github.com/xi816/gc32-20020
A 32-bit CPU, that was actually mentioned in CGovnOS way before even GC16X came out. But, it is assembler-backwards-compatible with the GC24 with minimal ABI changes, and also requiring minimal changes to the code written for GC24.
gcc core/ball.c -o ball # Bootstrap (use only on non-x86 platforms)
./ball # Build the tools and the emulator
sudo ./ball install # Install to $PATH
./prepare-disk disk.img # Build GovnBIOS & GovnOS
./gc32 -b bios.img -d disk.img # Run GovnOS on GC32
