Absolutely! So an ideal G2 would be for the U.S. to keep its alliance system with Japan and South Korea intact. Beijing would recognise Japan and South Korea belonging to U.S. traditional imperial sphere. In exchange, Taiwan would be reunified with the PRC, and Washington would recognise China’s dominion over the South China Sea and parts of Indian Ocean so long a U.S. vessels would be given free passage without interference. Both Washington and Beijing would work to stop the rise and militarisation of other powers like Japan and India. And here you go: you got a Concert of Great Powers (like Congress of Vienna) between US, China, and even Russia each hold dominion over their own spheres to prevent the rise of other powers. It means the three powers would not have to engage in life-struggles, whilst empowering other trouble-making middle powers, per prescription by structural realists.
