New "Blank" MultiBit .wallet File With Vanity or No Private Keys

[Sammey]

Is it possible for someone to either write a quick script to remove a key from a multibit .wallet file or create a new MultiBit .wallet file with either no keys in it (but multibit would recognize the file) or create a .wallet file with a specified key in it.

I'm wanting only Vanity Keys and Externally Generated keys in my multibit wallet. Is this even possible to do?

I would even accept an upload of a blank MultiBit .wallet file at this point.
