I think maybe minus the "Hutch moving on with someone else" part (quickly, at least), this is one of the most reasonable ending suggestions. The bit at the end about Christian does need something though, and I think (hope) that part of Hutch's resolve around the situation is because he either has a plan, or he's working on one. I think there is a high possibility of a bad end all round - Vivian loses Hutch (and maybe Sawyer), Hutch loses (pushes away) Vivian, Christian loses everything (either his business and any respect he has in the business world, or his life).
Hutch's plan there being to either completely ruin Christian, or to kill him. I don't know if I can see Hutch going so far as to kill him, but the situation means I don't think many people would be surprised if he did - the only surprise would be Hutch actually being able to go through with it (maybe that's Hutch's redemption - he puts a gun to Christian's head, after ruining his business, but then walks away, leaving Christian whimpering in fear, knowing that he's lost everything and has to live with that).
We know that Hutch is a numbers man and is being pushed in that direction (and away from sales) by Christian. Maybe that will lead to him getting an opportunity to either syphon all the business's money away, or to find and expose a load of corruption that brings the company down.
