How Cushing Could Fit Into Canon
You know that in The War Games Patrick Troughton left, right? Well the Time Lords said that they would change his appearence, not regenerate him. So the 2nd Doctor got aged, got partial memory loss and sent to an English country house. Susan, Ian and Barbara were changed too. Then after Dalek Invasion Earth, Dr.Who was sent back to Gallifrey where he regenerated into the 3rd Doctor.

The Curator
You know when Tom Baker said "It's the end but the moment's been prepared for"? Maybe the Moment took out of time for a brief few minutes, aged him and put him in the National Gallery, then took him back to regenerate.

Gallifrey
Because of all the Doctors saving Gallifrey? Well that changes The End of Time. Therefore he should still be the 10th Doctor.
