This is not a practice I have heard of before. Especially if the aircraft are being permanently withdrawn from service.
We used to do it at BA, brand new 744 arrived from Boeing first thing we did was remove and replace engines, just to space out the lives of each engine fitted so they didn't all need overhaul/mods etc at the same time.
I would guess put the newest engines on the newest airframes VV the old ones, some would be more saleable than others as a result I imagine.
