Hear me out: Mincemeat and Hello, Dolly! crossover. Like, Hello, Dolly! but the cast is just replaced by the MI5 gang or vice versa
Monty and Charles would be Cornelius and Barnaby, Hester and Bevan would be Dolly and Vandergelder, with the right tweaks of character and storyline I think this would make for a really fun concept. The two shows are pretty tonally similar too, with the glitzy joyousness of it all.
