Can I changing hardware for removing icloud lock?

Hi..

i have two logic board iphone 5

one is locked icloud

and another one is broken, i dont know what specific but this one is battery drain fast even not using it and is hard to find what specific hardware which causing this problem

And then i see on youtube who guy transfered the 3 chip (baseband,hdd and eproom ic) from broken logic board to icloud lock logic board

my question is.. it will work? If it work i want to try it.. i know its gonna be hardwork for board level repair.. but i want to do this than trowing this two things to the garbage
