what we really need to churn out some more maps is a collection of guys who know how to use the TE or at least have the skills to do certain things,
lets say coombzy learns how to lay down spawns and draw the roads leading to town and can now setup 1 spawn point, he can then do 5 or so in the space of 2 hours,
sirnuke then learns how to paint a mountain with all of the required brushes, snow , rock , rock grass, grass. He spends 2 hours painting mountains.
wpeters learns how to do picture perfect coast lines and spends several hours finishing those,
everyone re-uploads the map once they do their little bit and log their progress.
This is the only way I can think of to deliver more maps without relying solely on the sanity and free time of one poor person. The Terrain team have their hands full creating real world historical maps for the CM team and special events. Including updating and adding stuff to existing maps.
