There is a limit to how much VR can be done right now as is, what you are trying to propose is insane.
Unlike certain things, Halloween Events like Horror Nights, Scary Farm, and Dark Harbor are supposed to be experienced without the need for some kind of headset and/or viewing device that can change the perception of what the person sees.
Now, there are exceptions to the rule, but most of the time; those exceptions are more for experiences outside of the Mazes that they offer (IE, Legendary Truth from HHN25, Darren Browns Ghost Train [Before anyone tells me I am wrong, it does use actors to some regards], and other experiences that may need the VR/AR usage). Plus, comparing Motion Simulators to Virtual Reality Coasters is like comparing a mountain and a oasis, they don't mix.
