Agreed. Our Lancaster is ALSO a Mid-war ship. The Mk. III doesn't belong in the EWA or any early war scenario.
As far as (multi-engine) bombers, I think:
B-17D and F
B-24D
Lancaster Mk. I
He-111
A couple other Ju-88 models
SOME Russian bomber (I'm not as familiar with the Russian iron so would need some help, there)
G3M "Nell"
G4M "Betty"
Ki-21 "Sally"
Ki-49 "Helen" (nice mid-war step between the Sally and the Peggy we already have)
are glaring holes in the setup. I'd also like to see the B-25J--which I'll have to double-check production, but I THINK was the most-produced type--added to round out the Mitchells (we have the early glass-nosed and strafer in the 25C. The 25H gives us a good mid-war super-strafer. We need the late-war glass-nosed bomber, and I'd KILL to play with the 12-gunned J strafer
).
