First of, well made post, good job. Future suggesters take note: That's how you make a suggestion!
I love these big birds, the sheer amount of damage they can deliver just with machine guns, let alone the amount of explosives they carry. The sad fact is though that there simply aren't any maps for it in FH2 nor is there a gameplay that supports it. In a way these bombers don't have a role in FH2.
The Short Stirling is classified as strategic bomber, this means it was mainly used to level buildings or objects of strategic value, fuel dumps, factories etc. FH2 offers more of a tactical experience, where tactical bombers like the German JU87 Stuka fits perfectly.
However I'm not going to say that we'll never include it. One of our mappers might go nuts and do a special objective air map where one team has to defend points of strategic values such as fuel dumps or factories, while the other team tries to destroy it, as for example: FH1 "Bombing the Reich".
No map in that gameplay style is planned though and I have little hope of that happening any time soon.
