Seems like a good idea.

And then the entry point also needs to be fixed somehow: Jumping to
0xffffffe000000000 without pagetables won't work.

As far as I understand it, it's because Linux's linker script[0] doesn't
set a physical address. (It sets the virtual address to PAGE_OFFSET,
which is 0xffffffe000000000 in the kernels that I have built.)
