Default Motherboard replacing

I crashed my lg g2 (see this thread: http://forum.xda-developers.com/show....php?t=2747779)
And I was wondering. What if i replaced the d802 (international, I live in the Netherlands) motherboard with an T mobile motherboard (what Im planning on buying through ebay) and than unlocked the phone so it would work on my dutch phone carriers.

Is there any possebility that this might work?
