. I would have hoped that kind of thing was done already, though someone may be wanting to revisit their ideas in the light of what they've seen in this incident!
Was done what?
I doubt recreation of chain of events had been done in this case, it takes time to set it up, it is much more expensive proposition than fiddling with just ELT in the lab environment. It may not be as hard as NTSB's multiple attempts to reproduce sparks in the 747 main fuel tank but it may be difficult and time consuming nevertheless.
