Is there a way to get both sets of loot at the end of the mysterious car park?

I thought I figured it out. I shot the bomb on the right and disabled the flamethrower on the left. Then I utilized my gamma gun to set off the bomb on the left you can't shoot. Everything was still there in each room. I opened the right room first since that flamethrower was still active and nothing set off in the left, but when I walked into the left cell, it's as if the trap went off.

I'd like to think I found a loophole, but Bethesda automatically corrects itself lol

I have tried countless times trying to get all of the loot but every way I have tried ends in the other loot being incinerated. I believe there is no possible way to get both, which makes sense as it is, in a sense, trying to teach you that sometimes you will have to sacrifice something to get another thing.

You can't. I've tried everything save breaking the game. You can't legitimately get into both cages without at least one of the items stashes getting destroyed
