Definitely possible. We have not tried, but you make the plugin to work on a VR device. The main idea is put the spatial map relative to the camera when it is detected. The plugin is open sourced, so you have full control of how objects are displayed in 3D. It may require both knowledge in EasyAR and VR.
We have no plan to directly do this at our side in a short time, but we can help with technical problems when you are trying.
