[The Shining/Doctor Sleep]Would it have been possible to 'clean' the Overlook?

In Doctor Sleep, Dick Halloran gives Danny a lock box and tells him to memorize it inside and out. Afterwards, Danny is able to lock away the spirits of the Overlook that have latched on to him. Dick also tells Danny he can have as many lock boxes as needed.

If you had several people with the shining, and they all had mental lock boxes, could they have cleansed the Overlook?

I got the sense that the hotel site itself was somehow corrupted rather than it just being a place where multiple ghosts had accumulated. So even if you ghostbusted Roger, the tunnel child, Grady, etc bad things would continue to happen.
