I think that Matt would be a good addition and he and Jenna could stare at each other and wonder 'HOW ARE THESE OUR LIVES?!' quite a bit. It might help ground Tyler a bit too.

THE CONVERSATIONS THEY COULD HAVE. Oh, man. I want this so badly now.

Oh yes, the vampires, who are painted as 'completely insane predators with no redeeming qualities' are actually the ones who have the best family around, because they are WORKING at it. And they don't discriminate, unlike the werewolves.

It's kinda hilarious, yes. And vampires are also better at keeping their word than either witches or werewolves!
