Alan should be the 12th doctor
Heck, most people are convinced he's British anyway... and it would fulfill the doctor's dream of being a ginger.
Alan, a Texan Dr. Is quite a stretch - how do you view Idris?
Word is he's in the running for the next Bond - why not the next Dr.?
That said, itsn't it time for a female Dr.? We have female Time Lords ( Romana comes to mind); why not Dame Dianna Rigg?
