The regulatory requirements if required do put quite a damper on this plan. But wouldn't coinbase, Mtgox and the banks technically be performing the exchange portion of this transaction? We would simply be using their services. What's the difference between this process and me simply buying coins on coinbase, selling them directly on Mtgox and wire to my US bank , besides taking months for an withdrawal to process? If we keep records of all cash flow and prove to the IRS were paying appropriate tax, I don' understand the issue.
