This is a wonderful idea and the benefits are many including increased tourism to Cambodia and an increase in the population of wild tigers. However, it will be completely useless unless it is accompanied by a clampdown on the poaching and trafficking of animals/parts. The majority of this finds its market in China. A combination of education for those wealthy but peasant like superstitious Chinese consumers and long prison sentences to those found guilty of both crimes.
