This is all hypothetical, of course, but: you don't have to lose all your baby teeth in order for your adult teeth to come in. Somehow an adult tooth coming in causes the baby tooth's root to dissolve (if that's the right word) and then pushes the remaining baby tooth out of the way. So you might not need to lose your adult teeth in order for the next-gen teeth to come in.
