Someone else with more resources could perhaps try to get this done.
There is going to be an Avatar sequel, according to James Cameron. What if there was a competition and rush to design a load of concepts for creatures so that there would be enough for the film? Although Avatar was absolutely amazing and I had to see it 5 times to get enough, I didn’t think that there were enough creatures. Furthermore, I see creatures from time to time on this site that impress me more than the ones in the movie, even as plausible alien animals.
The art on this site never ceases to impress me.
