Ah yes, that'd be nice.
I'd just love to see how the personalities would clash against each other, if 10'd remember The Day of the Doctor, or 11 The Time of the Doctor.
How different would 10 seem in the trio, or how would 12 clash, or work, with 11.
Yeah, I'm wondering that too. Not fond, at all, of 9, myself, but, sure, he has his fans, and was fine enough with Eccleston in The Leftovers, Thor: The Dark World, etc.
Any idea why 9 isn't involved in that? Because he doesn't have a comic, unlike the other 3, or because there wasn't a clear idea how he'd fit into proceedings, or work?
