Bubble Plot - can I drag and drop to combine two bubbles into one?

I use bubble plots to render images in RGB space and was wondering if it is possible to drag and drop one bubble into another to have them added to each other such that the dragged bubble takes on the color of the destination bubble and updates the source image accordingly. I suppose it would be nice to be able to similarly drag and drop to combine two bar graphs as well. So, I guess I am asking if any plots allow for “drag-drop-combine” function as a way to edit arrayed data?
