No problemo. When finished you can use all stuff I've made as you wish.
Anyway, hilly stuff gave me an idea about two-part Alien base attack mission: Aliens digging/hiding "bunkers" and main base entrance in hills, instead of obvious, easy to spot (from the air), Alien-ish constructions. This way will be possible to create three terrain variations (that depend from base placement on the globe): forest, mountain, and desert.
