A few thoughts:
"Modyford" is perhaps not the best model to use for Captain Hook. He might have suitably long hair but he's a chubby chap, looking more like a stay-at-home aristocrat or governor than an active sea captain. Even if his head was transplanted onto the "Corsair3" model, he'd still have the same chin, or lack thereof.
What happens when a pirate with a hook fires a pistol? In reality, he'd probably shoot, then either throw the pistol away or put it in his belt, then draw the sword, so he's using his good hand for both weapons. (Most likely so would anyone without a hook - if you're right-handed then you'd use your right hand for both weapons.) In the game, you have the sword in your right hand and the pistol in your left. The game doesn't care what your left hand looks like; it draws whatever appendage is provided there by the model, be it hand, hook or tentacle, then puts the pistol in place. So this is what "Corsair3" looks like with a pistol:
By default, Captain Hook currently gets the "HMS_Bounty", alias "Armed Merchantman", which is a suitably small ship for a starting character. In the TV series
Once Upon a Time there is also a Captain Hook, played by Colin O'Donoghue, whose ship is played by the
Lady Washington, quite a film star in her own right. And we now have that ship, as "US_Interceptor":

Perhaps use that as Hook's ship?
