I tried to do this (getting more space for kernels in the EFI partitions) some days ago, and failed on my first try also, I went the easy way backing up what I had and deleting, remaking the partition using gparted, put the stuff in there(and finally change from gummiboot to bootctl), reboot and failed, after sratching my head and 2 more fails trying FAT16 and going back to FAT32 booting, I noticed I had not set the partition type only the label, and didn't found how to do that using gparted, so went to the basic: gdisk, and set the partition type to EF00 and I it worked. Didn't you miss this sort of details?
