I'm not sure if it's possible because I haven't tested this particular setup. Dealing with two connections seriously complicates things because it's basically tiling two resolutions like NVIDIA Surround does. You would have to add 2880x4320 to both connections, but you also need the original extension blocks with the tiled display topology data blocks, and I'm not sure if NVIDIA's driver will even consider non-native resolutions when tiling. Even if that worked, the monitor might not accept custom resolutions. NVIDIA's GPU scaling doesn't seem to work with tiled resolutions either, which is why you can't get 5760x4320 with SRE. 2880x2160 works because it scales that to 4K instead of 8K.
