I don't see why you shouldn't put your best pickups in your best guitar. That seems like a no brainer.
on the other hand, I like to suggest a magnet swap in the SE pickups before replacing. If the SE245 pickups sound too harsh, swap in an Alnico 2 or unoriented alnico 5 magnet. Especially the bridge pickups can be sort of compressed and nasally sounding, swapping magnets can open them up and make them sing, and it only costs a few bucks and takes a few minutes to do.
