I haven't duplicated exact bag styles, but I certainly would if the opportunity arose. I like Suz's solution and am glad to hear you are pursuing the teal and snakeskin.
In response to Jaime's concern, I have used my Rebecca Minkoff backpack in NYC, and I like it because of the ability to latch the bag on top, covering the zipper, rather than at the bottom, exposing it. On the subway, I would take it off my back and carry it in my hand.
