I would think that because the first few years are devoted to maturing and not fruiting, you should be fine. put them in fridge, they will start sprouting within a couple of months. Then put them into some little pots until next spring when they should take off. Cold winters should not be needed for developing seedlings. ( I think....)
Also, more than 1/2 of all stone-fruits I have grown from seed were very tasty. Out of three, I would imagine at least 1 or 2 would be pretty good and if not you will have some well developed root-stock.
