You can sure keep it quite a long time. But I believe the limbs loose some of their energy quantity after a while.
My buddy had limbs replaced on an older Martin bow(5-6 years old).
and we chronographed it w/ the new limbs at 14fps. faster than the old ones. It could have been better material design in the new limbs,but it really opened my eyes. A bow takes alot of abuse when shot. Other than the parallell limb bows, conventional limbs configurations take much more because they travel a greater distance.
I'm no engineer, but it only makes sense to me.
Of course that's not to say you can't shoot it. You can & my friend did,very well. Just not what it was.
