Can you create a plane from vuforia target images?

I have three vuforia target images in unity and need to create a plane from them. The target images are not on a flat surface, they are at different depths. Is it possible to generate a plane using the three targets?

You are under the assumption that placing image targets at different depths would result in depth difference in augmented space. It wont. It will simply detect image targets wherever they are. However, you can instantiate planes upon detection of the targets at required heights. The reference here being origin at corresponding target for each plane.
