I doubt this is going to fly. seabios has to do quite some low-level
stuff (like running code in real mode), I don't think UEFI applications
can do that. There is a reason why CSM was designed in the first place.
Note that you can build seabios as CSM for tianocore already.

What is the point?
You can just run tianocore as coreboot playload.
Drivers are not an issue, unlike arm x86 has standardized hardware,
tianocore can handle things just fine.
