Great discussion.

I know the FAA Tech Center (In ACY) does active research on the things you are discussing. Also, CAMI (In OKC at the MMAC) does the human factor and physiological research.

At this point, does this become an issue determined by cost vs risk for operators?

See? The labels were removed! no problem then, right?

As for the original question of making a "bomb door" or I'm guessing a B-29 like bomb bay.

Initial answer is: no

After some thought: HELL no!

Ok, let's go through the time and expense to make a set bomb bay doors on , say, a B747. Doors on a pressurized system are expensive, heavy (meaning less cargo weight meaning expensive), and more complexity (more expensive) and more maintenance and inspections ($$) and no guarantee of success.

Also, we haven't considered how to evacuate the main deck cargo.

It took the 2001 terrorist attacks to get solid cockpit doors on airplanes.
Cargo drop doors will NEVER HAPPEN (in standard cargo airlines).

Another consideration:
No one cares about cargo planes crashing.
Ok, not "no one" but it doesn't have the emotional response that passenger planes have.

An airplane crashed
people: "oh my, that's horrible!"
A cargo plane
people: "bummer, any pictures?

So instead there are mitigation procedures:
Hazmat laws, checks, as mentioned above: knowing where the bad cargo is to make it easier to fight.

Can't fight the fire?
Get on the ground/water pronto.
Unless it's mountainous (you're screwed)... or arctic waters (just as screwed), hostile territory (ooh, yeah, that's a good time), densely populated (screwed with innocents).

Makes me slightly depressed but no more surprised that there are people like yourself who exist in the world.

At least it sparked a good discussion.
