So I have a Heatwave from the Nexus Prime Botcon set, but none of the figures. I'm interested in displaying him in his combined mode, but I need some limbs! I was looking at possibly customizing some arms/legs from other robot-esqe figures as a cheaper alternative than springing for some combiner limbs that honestly don't look all that good anyway. I really don't know much about Gundam figures other than they look really cool, so I was wondering if the 1/100 scales figures might be an acceptable scale to kitbash? Any figures (Gundam or otherwise) you guys can recommend that might make suitable limbs?
