You can make it work mostly that way. Create a UKI (unified kernel image including EFI stub loader, kernel, initial filesystem and kernel parameters), then tell uefi to directly boot it. The four steps still run, but using only a single file.
Arch and Gentoo wiki only mention systemd-stub, are unified kernel images not possible with other init systems? With efistub seems possible but i couldn’t get that to work on my MB.

Edit: i found something to Alpine Linux.
Is coreboot doing something like this?
