Hhhmm, yeah I imagine he would be awesome, although like you I like Stefani as well.

Other than his coloring I don't see a similary look-wise with TP. Actually, other than Clooney---and even he resembles TP more in the 'idea' of it with the dark brows, etc. as opposed to any real resemblance----I can't think of anyone that even comes close to resembling the man outright, imho.
