Of course, you are entitled to your opinion however the reality is that this is unlikely to happen. My view is that species management is a primary responsibility of zoos, and a role for curators and senior keepers.
These days, the responsibility for a program lies with the zoo, not the individual doing the role. ZAA monitors them intensely and intervenes where programs are not working. Programs are removed from zoos if they are consistently badly managed. ZAA also provides training in species management.
One thing that pops up in the discussion on this site is the claim that some programs are badly managed. It is one thing to through broad accusations around, but nobody seems to want to name programs. My feeling is that most programs people here think are badly managed fail because zoos are not prepared to provide enough spaces for them to be successful.
