First, for those who assume that the system is not so bad, and who accept that the US dollar should continue to be effectively the major, if not absolutely the exclusive international currency, the idea would be to restore the system as it was before the 2008 financial breakdown along with, perhaps, some minor regulatory reforms (most of which are essentially more cosmetic and rhetorical than real).
This is exactly what the Stieglitz Commission and the Stieglitz report aim at. It accepts that the US dollar should remain the almost exclusive international currency (with some minor concessions). But it also accepts the right of the US government to manage the currency exclusively and on its own. As for everyone else, they have to adjust to the US dictates. This is, of course, not acceptable, especially for the South.
If the Europeans, the British, the Japanese accept it that is their business. But I don't see why the Asians, the Latin Americans, the Africans should accept it. And it is not accepted, certainly not by China and some of the emerging states - India and Brazil in particular. Although it is not accepted morally by African states, in practice they have completely accepted to submit to its consequences - they have done nothing to respond to the challenge.
So, that is the Stieglitz style solution. And it has completely failed. Nobody pays attention to the Stieglitz report, which has been dropped in the waste-basket, and nobody really cares about it. It has not convinced the partners, especially from the South. Even the North does not give any consideration to the recommendations of Stieglitz.
