More to the point, the Mosquito specifically and also the rise of Fighter-Bombers in general during WWII showed the way to the future.

The problem that is thinking out of the box wasn't strongest side of the air command (and still is), don't forget that they sent a waves of unescorted bombers believing into Giulio Douhet theories until the losses were way too high. Also it was proven for a long time ago that fighter escort is essential.

In any case I'm not sure that replacing entire B-17/B-24/Lancasters fleet by a Mosquitos would be right decision.
Yes, they are much more accurate but much more vulnerable to AAA. Also if you don't have air superiority and you put a decent CAP you still can loose some.

It is ideal weapon for surprise missions but probably not for strategic campaign.
No one tries to build a modern B17 equivallent.
Yes they do:
Either to get over a target:
Or to shoot from a standoff range:
