Doing stunts is for when you want it to look realistic.
If for this film project "it doesn't have to look realistic" why not use green screen?
Anyway here is my answer to your question..
This is a simple stunt. You can even show the harness holding up your actor which makes this extra secure. You don't need to be a stunt professional to harness someone and lower them at one of those wall climbing places.
Caveat: Simple stunts like driving down an empty road can have consequences. Some people are really bad drivers and uma thurman crashed into a tree with a one-vehicle accident. How does something like that even happen??

IDK but accidents do happen and maybe your actor rolls their ankle when they land ya know?
