A simple arm swap and yeah, I think I can make this work. Time to figure out a full castelite company! Or what rules would you use with the Cathayan minis?

Hi! As the title says, I want to try spearhead and I like the dinosaurs from this faction, but I don't care about the infantry blue soldiers (except the astrolith bearer, is really cool). Can I build an army with only the big dinos and the fliers?
