Sadly, nothing comes to mind. I wrote a review of Iris Gris here:
For what I can come up, I'd say an even colder and intense Iris Silver Mist without carrots and doughs, and with a touch of the peach of Mitsouko and just a tiny mini bit of the (horrid) drydown of Bas de soie. Iris Bleu Gris doesn't smell like it, and the impression is completely different, not cold enough, too fruity. (I have not smelled Irissime, so I cannot comment on that)
You should nonetheless smell the excellent La Pausa, a very fresh, natural, and relaxed iris. It is a completely different interpretation of iris. I remember somebody comparing a perfume to a nice girl in violet eyes - I forgot if it was about this - but the metaphor is perfect for La Pausa. Iris Gris, instead, is the most elegant, unreachable ice queen.
