Yep, very plausible as Spock. The dorky hairdo seems to fit him.
I mean, think about it. You're an actor and you take this role with the World's Dorkiest Haircut, these ridiculous too-tight costumes, weird pale greenish makeup, shaved eyebrows (sending the Heroes
fandom into mourning) and pointed ears
. They couldn't make you look more like a clown if they tried, yet you're still expected to be cool.
