Consider the spacetime around a large mass antimatter object. A small mass antimatter object will move in a geodesic path equivalent to both objects being made from matter. In other words spacetime is "convergent".
Spacetime is still "convergent" if we replace the small antimatter mass with a small mass since spacetime curvature is determined by the larger mass.
What happens to spacetime if we have small antimatter and matter masses in the presence of the larger antimatter (or matter) mass?

Yep .. I'm with ya, man.
Using the deformed rubber sheet model, perhaps the spacetime 'dimple' around the anti-massive object, simply dimples in the opposite direction from that created by say, a normal matter object ? In either case, the effect we'd observe from Earth, would be the same ?
The interesting bit may be where the two fields interact .. and maybe this isn't all that interesting anyway … it happens all the time in electromagnetic fields.
