No, I don't think it can help sorting out any fundamental problems.  nature that they could be resolved without having children too. Otherwise, the foundation of your relationship is wrong. If you need the children to sort out the problems and fix the foundation of your relationship, then the child(ren) will become the foundation of the relationship. 

And children will leave the house at one time, leaving your relationship again in a bad state, without foundation. And most probably in an even worse state.

Besides, children can feel very well if the relationship of their parents is not well founded, and will carry the burden of that.
