I love the idea of having a miscellaneous mod to put your fun side projects! Is this where the donkey might see an official release?

I see what you mean with something like a Griffin and Hippogriff. But there are a few that have features that Impossible Creatures alone cannot recreate, like the Amphisbaena (a snake with two heads on each end) and a Hydra (a creature with three or more heads). But it is your decision.

I thought about that, but realized that most of them are just combinations between human and an animal or an animal and... another animal, which is kinda the point of IC :D. Centaur seemed funny since you can now create other "taur" creatures, elephant-taur, ant-taur etc...

That being said, I have 2 more half finished fantasy creatures that have been sitting in my unfinished folder for some time, so those will be added at some point as well.

This could easily be a Mythology themed mod.
