Merging two EFI's into working one

I have one EFI (built by me) with working most stuff but sound, bluetooth, card reader doesn't work althrough I added required kexts and the second EFI (from web) which is older but has these three things working but it's buggy. Can someone help me to merge things from these to my EFI
