TBBT and Universal Monsters

[ShennyShipper91]

So i was thinking there could be this episode where Sheldon and Penny are married and host a Halloween party and the theme is Universal Monsters; so Sheldon and Penny host as The Phantom of the Opera and Christine Daae, Howard and Bernadette attend said party as the Wolfman and Gwen Conliffe, Raj goes as The Mummy, etc...
Any other ideas for the other characters or as to how this episode would play out?

I just love the Universal Monster franchise and the Shenny
