No. Once you start mixing bootloader versions with system file versions (i.e. 4.4.2 bootloader with 4.2.2 system files), RSD Lite won't work. You will have to use a command line and mfastboot.exe to manually flash each partition.
And I actually tried to run 4.2.2 (post camera update) system files with a 4.4.2 bootloader and it would not boot; however, 4.4 system files do work with a 4.4.2 bootloader.
This has actually been discussed at great length and detail in this forum and A LOT of people were bricking their phones playing around with bootloader versions, just like you are talking about doing. At one point there was a sticky dedicated to it, but its since disappeared from the board for some reason.
To put it simply, please don't start mixing bootloader versions with system files. If you like 4.2.2, don't upgrade to 4.4.2. If you are on 4.4, then you can still downgrade to 4.2.2 (post camera update version). Do that and stay there. But if you upgrade to 4.4.2, don't fool around with it and start trying to downgrade. There is no point, and you will likely end up bricking your phone.
It's your phone, so do what you want, but you have been warned (by someone with personal experience by the way). If you do brick it, please don't start another "OMG! HELP ME!! I BRICKED MY PHONE!!" thread. There's plenty of those already floating around here.
