Yes.  Each spatial index would need to have its own "global" coordinate system, and either all geometric objects in the index would be assumed to be in that coordinate system, or each object's entry in the index would need to be accompanied by a transformation from the object's coordinate system to the index's.

I'm not sure which is better really.
