This might be a great idea, especially if you want your dinosaur to be nore unique.
It's simple, someone makes a custom secondary attack animation (And maybe primary?) in SDK and uploads it to the Store.
This would not only make your Dinosaur Character more Special than the other ones, but It'll also make the game a little less Repetitive.
Obviously the animation should stick up with the original attack
The Video Below is an Example, made by Will I Believe.
As a Note, the animation should not be shorter or exceed the original duration of the attack
hollow nebula
Some animation upgrades are cool, however I do not think you should pay for this
final tide
Free Drops maybe? 
fickle raft
I personally do not think these should be cosmetic items, I feel this would really mess with visual clarity
gusty charm
This, it looks much more fluid
fickle raft
I agree with that yeah I like that new one a lot more
gleaming pawn
If you could just make that an update and not have people pay for custom animations, that would be way better
stable lynx
Honestly that animation should replace the current one. It's 1000% better

What I think you can do, if dino is up for it, is just create more variation in animations like how rex has 2 different human eating animations.
Have 2 or 3 animations for acro stomp, pick one at random each time it is used.
Even then, in a lot of cases the animation would be too specific or quick to really add variety to.
boreal mountain
^ that
next geyser
wait rex has 2 different eating anims?
boreal mountain
I think it would add some variety without potential P2W allegations if the anims end up being different enough, such as in this example where the Acro throws its head around wildly VS the current that keeps it in a very steady position

wait rex has 2 different eating anims?
2 different roars too
snow brook
iirc tyrant eating anims depend on which way the human was facing tho
