If you look at the General Image Module in PS 3.3 section C.7.6.1, you will notice that Instance Number (0020, 0013) is a Type 2 element. That means it can be empty. So, you should not count for it to be unique at the image/instance level.

Yes this is possible and 100% legal DICOM. The only instance level unique value is the SOP Instance UID.
