The EFI partition doesn't have to be RAIDed. All you need in the EFI partition is a stateless, RAID-aware bootloader that is hardcoded to look for a RAIDed volume matching a generic label (such as "rootfs") and then chainloading the actual bootloader from there. Then you can just install this "shim" bootloader into each disk's EFI partition once and you don't need RAID or to even mount it ever again.
