The TreeMaps use the values of the leaf nodes to calculate size and color of the parent nodes, and there's no way to override that without faking the chart into believing that all nodes are the bottom leaf nodes.
I suppose it might be possible to backwards calculate the values you would need the child nodes to have in order to get the size/color of the parent nodes right, and present the TreeMap with a DataTable that reflects those values, but doing so might prove prohibitively difficult to implement.
