Yes, provided that there are no fighters, that the GV killers are the B-25H and IL-2, and that all the anti-aircraft vehicles are enabled. You may also want to limit the number of bases that the planes can fly from, just to prevent everyone from running straight to them.
EDIT: I honestly don't see the logic in using the P-38 and Bf-110 for GV killers. To kill GVs, both those planes are realistically going to have to be dive bombing, effectively giving the GVs no chance to survive. In addition, people will doubtlessly just begin dogfighting with them, and thus defeat the whole purpose of the GV-oriented setup, IMO.
