The point is that QI is generally presented as something that's not terribly difficult for someone to test out. The biggest barrier to entry is understanding enough physics to create the quantum noise, but after that it's basic robotics that can be done cheaply and by a single person. Changing the experiment to require 1. illegal acts i.e. betting on someone's death, 2. knowledge by others, introducing an interference factor, etc changes the thought experiment. Of course, it may be valid as a thought experiment if it adds an interesting new complication, or removes a complication that wasn't essential to the paradox. But remember, the objection you proposed your scenario to avoid was the possibility of something going wrong with the suicide attempt. Changing the entire scenario to be less plausible seems a bit too much for a staightforward objection like that.
