You must either be a steely eye'd killer at a secret airbase in Lincolnshire or a bloody lucky 4-engine airframe driver.
The latter has probably already been a display pilot.
Lancaster pilots started as 1 GSU pilots. Then some bomber types like Ken Sneller (I flew with Ken) then other 4-engine multi like Mike Chatterton until he was in the right place at the wrong time and the staish thought he was too low over the cathederal. Then DT of Vulcan fame.
You could say a C130 tour might be a good route.
