Yes--you could make paste sell for the same prices as toxic waste but be able to carry 1000 of them per cargo unit. One server I was once on made a "volume less commodity" (by mistake) and you could carry an infinite amount. You can easily use this method to make selling synthpaste as profitable as cardamine--and if you make the best selling points in Kusari and Rheinland you have natural enemies (FA and LWB and their allies).
