No, don't do that for an "install" kernel, that way is madness, just use
a real UEFI bootloader which can handle an initrd and the like properly
(like gummiboot, which arch is using for their UEFI bootloader, and I've
been using for months quite successfully.)
Only boot a kernel directly from UEFI if you build your own and have
customized it for your hardware. Some bioses will let you do this in
secure boot mode without having to sign anything, I took a video of this
on Friday showing how easy it can be:
