Interesting. So if I enter a coordinated turn, the G force increases.
If I enter a descent, the G force decreases.

More specifically, the G force induced by gravity is constant. As you
accelerate the aircraft by changing its direction, the total G force and its
direction acting upon you as the pilot also changes. You cannot eliminate
gravity, so there are some things that are impossible: for example, in level
flight, you cannot make a coordinated turn with a 90-degree bank, because that
would require a vertical component of zero in the acceleration forces acting
upon you, and the presence of gravity prevents that.

When you enter a coordinated, level turn, the G force you feel increases, but
its direction does not change. If you enter a descent, the G force diminishes
as you accelerate downward (your downward acceleration being subtracted from
the force of gravity), and then returns to 1.0 once your vertical speed is
constant.

What happens if I do both of these things simultaneously?

You get some combination of the above; there are several possibilities.
