first off, I'm on vacation with my family, typing this on my stupid iPad whose autocorrect is driving me batty so if my details seem sparse, sorry, I have typed this info with more details before, search.
if you are talking about custom, 3rd party rooms, maybe... As it depends on what parts they flash, and what their base is.
But if you are talking about moto roms, then NO. Do not, unless you don't mind turning your X into a brick or paper weight.
Again stop thinking about htc s-off and what you were able to do as it doesn't apply to moto. Coming from an Incredible and Thunderbolt with s-off, I know how it's hard to forget. And trying to compare the two will cause many questions,
Due to changes in the bootloader and gpt.bin included with 4.4.2 on the X, under certain circumstances when trying to downgrade from 4.4.2 to 4.4 or lower, you could either brick your phone, or set it up to brick in the future when you take an upgrade. So it is suggested you just stick with what is on your phone once you get on 4.4.2. If you have an unlocked boot loader you won't need to downgrade to root.
I've read, (not going to dig up the link right now cause I'm on iPad) of some who had 4.4.2 but successfully mfastboot flashed system.img only, and if they went into app drawer -> setting -> security -> they were kicked back out to settings. This is due to system parts relying on the other components. I'm not sure what other problems were found day to day.
Additionally there were/are many reports asking for help because their device won't boot. The common thread.... They had 4.4.2 and downgraded or tried to downgrade.
I'm not going to go into every possible scenario, what might happen, what causes it, what might be safe, etc. the general consensus is once you have 4.4.2 on your X do not try to downgrade!
