yeah, u could do all sorts but it'd be like the horses, u just get to see it ut its not the real item if that makes any sense, basically if u add/replace a magic (i would recommand adding) then u change the sounds with either nothing or like an arrow sound ripped from another game or just ranomdly found on the net then i reckon it'd work, as for stuff like images etc i'm sure u could rip one from another game like soma or something and the arrows, well take ur pick i mean u got zuma archers or archer guards...
