I can't picture it at all. I mean, the personality and even the looks of Carlisle and the Volturi are exceedingly different.
Carlisle is evidently compassionate, loving, caring, and wishes to do whatever he can do to help the human kind.
The Volturi, needless to say, is the opposite. They're clearly cruel, apathetic, cold, and humans to them are like candy...you eat them up and throw them away.
As for the looks...Carlisle looks angelic and innocent.
