If cuttings are thick enough and properly hardened off (not recent 1st year green growth), then this is possible. However, shelf life is not infinite.
Are you doing this as a backup plan in case one doesn't root? If so, I would suggest re-thinking it. If one doesn't root, it could be because it's a hard to root variety, or the particular batch of cuttings you have is suboptimal for some reason. In either case, if a particular cutting fails, there's a good chance that the whole batch of that variety is susceptible to failure (maybe not 100%, but 50%). In that case, refrigerating for the 2 to 4 months might further weaken the marginal cutting, thereby reducing your chance of a successful root.
So I'd say decide now whether it's more important that you have a tree, regardless of the cost, or if you want to do it on the cheap by keeping 1 of each and selling off the rest.
Or even better, as others have mentioned, if it's a sought after variety, you should be able to sell the rooted cuttings if you end up with extras.
