In short, hell yes! No doubt you could get a shaving edge off that hard if you know what you're about. Arkies have far more range than most other naturals depending on how the surface is prepped, amount of pressure, honing media (water, soap and water, the various oils, etc.). As others have said, spend a little more and step up to a true hard, surgical black, or translucent, especially since it sounds like you're new to Arkies and may not be able to max out that hard right away.
As for a good stepping off point, I have done many edges from Nani 12k to Arkie with stellar results. That said, lately I have gotten even better results going from my Norton 8k straight to my 14"x4" Arkie with about a hundred "windshield wiper strokes" on WD-40. But many including me hone on 6x2" (or even 4x1.5 on my old Norton translucent) quite happily and get excellent results.
There is really nothing quite like a well-done Arkie edge: just exquisitely sharp, precise and smooth. And there are many long threads on this and other fora going into great detail about surface prep (minimal with Dan's stones), various lubes and techniques. Let us know what you end up with, and how it goes!
