I'd rather not risk it, honestly. To go back to the CR tone, will be too much of a shift.
Casino Royal was not your standard bond movie, it was a great film, with Bond in it. If that makes sense. Rather than a Bond film, with Craig in it -it was a whole new beast. They were heading towards the classic bond movie, but when they got there, it seemed like they forgot the tone and spirit of the Craig movies and just made what they thought the fans wanted.
Spectre just didn't feel relevant, it didn't feel like 2015, it didn't feel like the world was at risk, Bond didn't even feel like he was at risk.
If anything, Spectre should have been a two parter when Bloefeld was introduced.
Start off with london and other cities being attacked, it shocks the world. But we see how this effects a city, what they do in retaliation, we see bond doing his homework, that there is this higher organization at work. It takes him all across europe, he finally gets a clue that takes him to a corporate event - there he learns powerful businessmen are fronting the attacks for their own personal gain, to spy on the governments. It's almost as if the terrorists are one step ahead and turns out a mole is in the ranks. Bond or any government worker tracking this is taken out, which leads to bond in hiding.
Bond misleads 3 key players, trapped in a safe house, to find the mole and it ends in a deadly shoot out.
Part 2.
MI6 reshuffled, M told to drop the search of the top dogs, obviously an insider or pay off, corrupt officials as per usual. Bond tracks down Blofeld to a secret base, army in tow. They storm it, get in, get information, destroy evidence and go back to london with information.
Bond wrestles with his conscious as it shows corruption throughout westminster.
On a break from his duties, bloefeld catches up with bond, hell bent on revenge. They have a personal duel where one is killed and disposed of, with no trace.
Life goes on.
Or something like that,
