Opening the two-day meeting of the G-20 finance ministers and central bankers on Saturday, Australian Treasurer Joe Hockey said support was building for setting a numerical goal for growth.
"I have a great sense of hope that this G-20 meeting will be able to lay down a real and tangible framework for an increase in the growth of the global economy over the next five years," said Hockey, who is hosting the Sydney gathering.
If adopted, the plan would mark a departure for the G-20, as previous attempts to set fiscal and current account targets have dissolved into bickering. And while a target would largely be aspirational, it would mark a sea change from recent meetings where the debate was all about growth versus budget austerity.
France's finance minister, Pierre Moscovici, welcomed a goal of lifting world growth by a total of 2.5 percentage points over five years, calling it ambitious but "not unrealistic".
A G-20 source said the Germans had withdrawn their opposition to setting an overall target, as long as there were no goals imposed for individual states.
However, not all the German camp seemed to be happy, with Jens Weidmann, head of the country's central bank, saying quantitative targets were "problematic in my view".
And Nhlanhla Nene, South Africa's Deputy Finance Minister, said there was still a lot of work to be done.
"For us, whatever the target is, if that target doesn't talk to our issues of dealing with inequality, unemployment, dealing with our growth, but also looking at the broader integration and making sure that we have a stable environment at the global level in which to operate, unless they talk to that it wouldn't mean anything to us," he said.
The plan borrows wholesale from an International Monetary Fund paper prepared for the G20 meeting which estimated that structural reforms would raise world growth by about 0.5 percentage point per year over the next five years, boosting global output by $2.25 trillion.
The IMF has forecast global growth of 3.75 percent for this year, accelerating to 4 percent in 2015.
The laundry list of reforms run the usual gamut of liberalising product and labour markets, lowering barriers to trade, attracting more women into the workforce and boosting investment in infrastructure.
"While the gains stem mostly from policies that countries need to implement for their own good, joint action could produce beneficial growth spillovers in the longer term," was the IMF's argument for pressing on with action.
Still there were no details on how or whether the G20 would police each country's progress on the reforms, many of which would likely be politically unpopular at home.
The onus would be on the rich nations to pick up the baton on growth from the developing countries, who had carried the world economy in the wake of the global financial crisis.
The emerging members have also been pressing for the U.S. Federal Reserve to try to avoid sparking market volatility through better messaging as its throttles back on asset buying.
There was never much expectation the Fed would consider actually slowing the pace of tapering, but its emerging peers were hoping for more cooperation on policy.
"I think if there was a "no surprises policy" in relation to monetary policy, and that central banks around the world have reasonable warnings of what may be events that do create market volatility, then I think that is not unreasonable," said Australia's Hockey.
Others were not so sure.
"I am sceptical about coordination in monetary policy within the G20", said the Bundesbank's Weidmann, emphasising that every central bank had to act according to their own mandate.
