Eh...I'd rather not go THAT far, since in doing so we might also have to ditch the entire Hunting Range, and given that it's one of the few real 65,000,000 B.G. places...no, all we have to do is rework the number of items used and the actual items gathered...perhaps replacing feathers with bundles of feathers(which are actually useful for, among other things, balancing arrows) and petals with skins. Hell...maybe we can even integrate a quality system...but let's not go that far if we don't really have to.
In any case, I see no need to ditch the system entirely...merely rework it.
