Aye. The falx animation worked fine with my modified Pharao's Guard, only they were holding spears. The swordsman animation worked for my triarii, but they had no weapons. My phalanx-capable legions worked fine with a long pike and javelin animation (although it did look wierd, but only because they held it like a javelin). If anything was strange, it was because I used the wrong weapon for the wrong animation, which naturally would be fixed if I actually could use the right weapon paired with its animation.
