It's unlikely that you would get anything if you tried hatching double yolkers. More than likely it would crowd out both chicks and they would fail to survive to hatch, if they did they would be small and likely poor do'ers.
The best shaped and formed eggs are always best, but there are some myths flying around. The rounder eggs do hatch, I've hatched many. The old timers say that a round egg is a pullet and a pointy egg is a cockerel. Of course I've never tested the theory, but the round ones do hatch, of that I can tell you for sure. The reason the more porous eggs are not ideal for hatching is that they're generally more susceptible to bacterial contamination, which would prevent the chick from developing normally. That and the humidity/air transfer can also be slightly different than a normal egg which may result in poor hatch rates for those eggs.
In general, just pick your very best eggs when you hatch. Is it a remote possibility that you could get that rare egg that hatches out "twins"? Sure, I suppose it is. But more than likely all you're going to get is a dud at best and a lot of heart break and a couple chicks that need to be put down at worst.
