Ditching the bootloader is possible:

It seems to me that you should be able to create a raid1 v1.0 MD array
of your EFI support partitions, and put the combined and signed
kernel/initramfs onto it (mirrored to all member drives).

Then set the UEFI bios to try each device's ESP in turn.

Untested ... :-)
