Please allow me to step back in for a moment. I'm pro-feather option.
To me, I think one of the main reasons JP chooses the non-feather version is that it is "scarier" as Dr. Wu said himself. There is a basis to it - as I think after separated by 65 million years of evolution, we might be genetically pre-programmed to have more fear in reptiles than in birds. Hence, it is completely understandable to opt for a non-feathered version as our first instinct. But please, do ask yourself - are you certainly sure that a feathered version can't be as scary? Before answering that question, please bear in mind to not limit your imagination based on what you seen. Go beyond that, work on it as hard as you can - to do it justice. At the end, one might reaches the same conclusion as the beginning but I see nothing wrong in doing that.
If you pay close attention to what Universal has done. You will notice that they never deny a feathered version dinosaur. Instead, I feel that they are uncertain on this position themselves. Not to mention that the lead advisor Dr. Jack Horner himself is the main proponent of bird-like behaviors in dinosaurs. All these said, what I'm speculating is that given if someone is able to come up with an extremely scary, but loveable version of a feathered Dinosaur, I won't be surprised at all the lore will go into that direction full swing. (After all, I have to admit that it is extremely challenging to do that and the chance might be remote)
Since Universal is not certain on this position themselves, I actually think they would be more than happy to do a trial here, in video games (no offense, I do happen to think that the video game market is not as wide as the movie market, correct me if I'm wrong). But of course, a serious trial with careful design.
Finally, please don't get me wrong, before seeing such an extreme version of feathered dinosaur, I will be among the first to stand up against replacing the non-feathered. But please.... I would like to repeat AGAIN, the host is NOT asking to replace, he is simply asking for an additional OPTION. We should never deny a person's dream. Please let the reality does the dirty work itself.
