Could be interesting. I still enjoy shooting with my Diana f+ with Instax back. Used it last in December when we went on the annual Griswold Family Christmas tree hunt.
We bought my mother in law a Fuji Instax 210 a few years ago. She really liked her film cameras and never gelled with digital. This way, she can take her pictures and then we got her a couple of those wire picture hangers so that she can change out the images whenever she wants.
