Sometimes mine crack in the winter, if I use too much beeswax in them. I have to back down on it in the winter and I up it back up in the summer. Not sure about the wicking, if those 2 wicks are gonna do the trick. Myself, I would try a large single wick. But if that is all you have, and it is poured already, I would give it a try and see what it does. That is what learning to make candles is all about right? Testing and experimenting to see what works and what doesn't. Best of luck to you!
