Unless it can completely stop poaching (which on its own I think is unlikely) I don't think it will solve the fundamental issue that drives poaching, that there is a market willing to pay exorbitant fees.
Ivory has zero physiological medicinal effects, but their rareness convinces certain kinds of (shithead) people that they "must". The rarer the material, the more "special" it becomes, driving up the price further and the higher the price, the more emboldened the poachers become.
