Does "should not" mean this is not possible with the current version of gstreamer? For video data fusion, I need to communicate forensic data acquired from one plug-in and pass it on to another. I was hoping to accomplish this through the GstBus. If this is not possible & I need to use a GstEvent, is there any functionality lost in using an event handler for this purpose?

There aren't any examples of that, since an element should not listen to bus messages from other elements. Generally events (including custom events) are the appropriate way for elements to communicate specific additional information amongst themselves.
