It seems to me that such things are possible in isolated cases. And it is unlikely that they will be ready to accept a large number of hunters. After all, this is a serious responsibility. Who will come to them? Everyone who is ready to pay. And there will be people with different levels of training, with different physical characteristics. How effective will they be? Will they create problems? Will they increase the number of accidents?
When a hunter is preparing for a safari, the host party has time to study him, understand what kind of person he is, how prepared he is and how serious he is. They provide this person with various services and at the same time are responsible for his safety. But if there are many people willing to shoot elephants, who will look after them?
Hunting an elephant with a bow is, of course, a very exciting activity. However, it is unlikely to be suitable here.
