I wish, it'll cost a million dollars or more to test at this scale and it would still be one data point. Instead I simulated these systems to test the physics.
But please, come help me do this test in real life, it will be fun!
Are you representing these devices to others as safe, with safety mechanisms? That is, are you selling or even giving them to people?
I hope only you are at risk from these devices (and I hope you are safe too, but that's your choice). Untested technology can't be depended on. As a rule I don't believe anything works unless I see it with my own eyes - if I swap in a new patch cable, I ping something. Safety equipment for mortal risks is on a different level.
Sounds like a sound design to me. If he gets sued at least he can argue he did everything reasonable to prevent and quench a battery fire. That's how gen 4 nuclear power stations are designed to cool the core in the event of a loss of coolant incident. The other way is to use LiFePo chemistry which doesn't ignite like LiIon but has half the capacity.

"Sounds like a sound design" isn't sufficient engineering; doing everything reasonable would include testing or using an existing tested design; and nuclear power station designs certainly are tested.
You've tested it, right?
