Matthew Yglesias looks at Jon Huntsman's op-ed, and says:

There are four ideas here. The first is to repeal Dodd-Frank's proposed mechanism for resolution of large banks. The second is to do what Dodd-Frank's proposed mechanism for resolution of large banks does. The third was proposed by the Obama administration and killed by the Senate and would only moderately discourage bank consolidation, not eliminate the need to do something when large financial institutions fail. The fourth is a good idea, but would penalize lenders of all sizes and has nothing to do with the ostensible topic at hand.

This is, I think, part of the problem with conservative discourse being so dominated by jeremiads against mythical Obama administration initiatives. What Huntsman wants to do, in essence, is repeal a made up provision of Dodd-Frank in order to replace it with what Dodd-Frank already does, add on something the administration already proposed adding on, and then do an unrelated tax reform. But he insists that he thinks Dodd-Frank is a "tragically" inappropriate response to the financial crisis.
