There was a comic artist (Rich Morris) on the net that was making a crossover Doctor Who-James Bond story. He has done a few other crossovers as well as a Ten Doctor's story. He hasn't finished it yet, but it covers the Doctor (various faces) encounters with James Bond (also various faces) and the idea that Blofeld was also an exiled Timelord who's TARDIS broke on Earth, deciding to steal the Master's TARDIS. Not sure if they came out and said Bond was a Timelord, but they did have two Bonds at once (transition from HMSS to Diamonds are Forever).
Also the concept that the reason no one believe James Bond isn't anything more than a novel or movie is that his has a simple trick that make people forget....His name (actually the specific pattern, "Bond, James Bond") The Doctor (10th) uses it on Donna, who forgets what they are talking about for a second.
So far its been the Tenth Doctor (with Craig Bond) and Third Doctor (with Moore Bond) and most of the Bonds, probably for time travel shenanigans.
Other things he has crossed with the Doctor? Jem and the Holograms (with the Sixth Doctor and Mel). Forever Knight (with the the Fifth Doctor and Nyssa, as the Eight Doctor). And a mention of Kolchak: Night Stalker crossing with Sarah Jane Smith during her time with the Fourth Doctor. (As well as an adventure with the Third Doctor to early Elizabethan times...before the Tenth Doctor would have married her)
All those actually sound pretty cool.
I wonder what the Doctor said to James Bond hehe..
