Damn, the search button REALLY works

Seriously though I was getting ready to put a set of OEM springs off my old 05 Base up for sale when I noticed that guys were asking if the springs were revised or unrevised. After further searching turns out that my 05 rears look to be revised.

I now have an 03 touring and am gearing up toward a coilover set-up (after winter) but will stay stock for the time being. My question: Would there be any benefit to installing my 05 rear springs even though the rest of the suspension isn't revised? OR would I cause some sort of imbalance by doing this?
