In a word.. No
Unless Joss ends up be executive producer for series 5 or whatever (hughly unlikely), then Doctor Who just doesn't fit. I'd never think to look 'Whedonville' for it.
As such, and putting aside a section of its own, then the general TV section is really all thats left.
Maybe if the Weta statues, etc take off and more custom work is done, etc then it may get its own section, but till then its best where it is.
The only other option would be a more 'british' sci-fi section, things like Doctor Who, Torchwood, Blakes 7, primeval (i'm sure there are others), but at the moment I don't know if there is enough from a 'collectibles' point of view (on this board at least), to go with that option either.
