[Q] Bootloader question :) topic

I recently updated my N7105 to the recent 4.4.2 Nordic ROM ( n7105xxufnd3 )that was floating round that tripped my Knox, which I dont care about.
When i got sick of the updates abysmal battery life i flashed the latest stable release of CM for the GNII LTE a 4.3 based ROM with out issues.
But I'd like to know if i can revert back to my original ROM i.e. WanamLite MC3 V1.3, a TW 4.1.2 based ROM, for its spen support, battery life, atpx and boeffla sound support (im a big music listener) w/ Wanam's Adam Kernel.

Can i do this with out running into any issues, despite the gap between a 4.4.2 boot-loader (as I've been told i cant roll-back from this version) to a TW 4.1.2 ROM?

Thanks in advance guys :)
