Sorry. No offense meant.
How about some weapon suggestions?
DUC becomes "Pea (pod?) Shooter"
Mines become "spores"
Plague devices become "Rot"
PDF -> Weed Whacker
Colony Types can become Gas, Rock, Ice hydroponics
Troops might be trained carnivours.
Racial traits can be translated into various ecology types: Arctic, Desert, Ocean, Garden, and of course the Vegan's.
Just some thoughts, good luck.
