I would have thought : create a linesegment that is the equator and perform an intersection between that linesegment and the target geometry to identify the point in question and then create a new geometry with the new point, or something like that.
I am not sure what it would mean to add a point to polygon crosses the equator - I would guess that would mean adding a vertex at the equator, in which case I think the intersection would return a line (I have never done it) and the vertices in question would be the points of the returned linesegment.
