With 4.4.2 the motoboot (bootloader) and GPT.BIN got updated. At least these two (and possibly other parts) prevent a 100% successful ROM downgrade to 4.4 or 4.2.2.
You can try to do as proxuser has said, and use mfastboot to flash only certain parts... BUT *IF* it is successful, you will have intermixed versions on your phone, so if you try and take an OTA in the future, it will fail or brick your phone.
I've also seen reports of people who downgraded only system and boot having issues trying to go under... Settings -> Security on the phone (it kicks them back out.
There were enough posts of bricking when downgrading from 4.4.2 that the general rule it is too risky to try.
