Sometimes more vertices is not the solution. In fact, unless there are very fine tuned bones specifically geared toward the toons you typically work with, the weird wrinkles are going to be part of the territory. I think Daz deliberately limited the versatility of G9 simply because a unimesh with more vertices almost requires it. They had to split the difference between masculine and feminine, which limits how far you can reasonably go. Which is why it is far wiser to split the morphs between the two genders and get past this limit, but also have custom toon character controls that allow those controls to work even better.
