Accelerating and simplifying booting

Linux does already support booting that way, through CONFIG_EFI_STUB and pair with CONFIG_CMDLINE, you can have a kernel know what to do when nothing gives it command line.

That is most simplest and favourite setup of booting kernel where the kernel has all compiled modules to use entire system and compiled in command line to know how to boot without relying on additional parameter given by other thing just tuck kernel bzImage into /EFI/Boot/bootx64.efi (or other name depends on architecture) with single cp and kernel is updated.
