Currently our theme for layers provides minimal functionality, in the future version we probably should use SLD Styled Layer Descriptor, an OGC standard (see http://www.opengeospatial.org/standards/sld).
Here is an example how Google Maps symbology can be configured using SLD: http://geoserver.org/display/GEOSDOC/Geoserver+and+Google+SLDs

I have been fixing the current implementation of themes/ styling to give better support in the current version. The following points need attention:
Another solution would be to support multiple attributes in a network coverage and use for 1d flow not 5 network coverages as output but 1 with 5 attributes and redesign the theme dialog to use 1 attribute for size and another for color.
