No. Weight is defined as the nett force you excert on an object as the result of your mass being attracted by gravity. Since the gravity is equal in each direction, you would indeed weight nothing. But you would feel a pretty high pressure of an entire planet on top of you. Subtle difference between weight and mass. Another way to look at it is using the concept of minimizing the potential energy in a system (which is a tendency of all natural systems). If you exchange a certain volume of the most dense part of the core (the center) with a less dense part (the crust) that requires labour. You move something that has a high mass against the gravity which requires a lot of energy, and you move something that has a lower mass in the direction of the gravity, which will only yield a little bit of energy.
