Excellent idea! Also this whole experiment is really exciting. I'd heard of quantum entanglement being demonstrated with larger objects, but this is the first I've heard of measuring gravity between small objects. It seems like this must eventually lead to quantum gravity, or. . . something else!
The issue is that gravity and quantum mechanics contradict each other only when the curvature of spacetime is significant, which is not the case here. Still, it would be amazing to measure gravitational field from an entangled object... But I do not expect to see this during my natural lifetime.
