"depending on the application" is the key.

strange things happen during accidents, so i won't recommend anything because of this.
when i was a fireman back in the 70's, i responded to a scene where a guy was trapped in his vehicle during a multiple vehicle accident.
his leg was trapped through the floor pan when the inner kick panel structure separated from the floor pan, his foot fell through, then the panels closed up trapping him. he was lucky to not loose his foot.
this particular accident had two fatalities.

now with that said, over my life i have built and modified countless items that have been against many "norms", some surviving "destructive" tests without any damage what so ever.
structural adhesive is a great product when used correctly, and i'm sure i will use it in an "inappropriate" application during my lifetime.
will it work out for what i will use it for ? who knows.........
just stating about me.
your results and mileage will vary.
