Phobia overcoming game

Well for the past few months me and my friend are thinking to create a VR game to overcome phobias such as acrophobia, aerophobia , claustrophobia etc

I have done some work on unity and have little bit experience of game development i need little bit guidance on this. The idea is to make a real life environment and such scenarios by which the user is afraid of and let him stay in this situation for some time to clear the level.

We also might need doctor to diagnose the symptoms and to tell us the way of curing it. I just need little guidance about weather this idea will be successful or not.

do share your opinions..
