It certainly isn't a foolish or over-the-top idea, but someone else said it best: seeing as it's a fan-made mod, and you're dealing with a VERY classic and VERY fixed universe, it is probably best to leave things as they are. Lord knows there are a million other things that these guys are attempting to do.
That would really change the entire balance and approach. I say they leave everything pretty standard until they get a beta going, and address balance problems from there. Who knows, maybe something like this will end up in an update, but it would be pretty huge, especially in urban situations.
