If the leak continued, and the fuel remaining were enough to warrant salvaging it, I would give consideration to restarting the engine (it musn't be the cause of the leak, if the with engine secured, leak continues, correct?) and continuing diversion with two engines. I might, as above, open X-FEED and feed both engines from the leaking tank.
Why not just fill the Ctr Tank with the Right tank Fuel (or at least to the gunnels) then feed both engines off the Right main tank, or, possibly feed From the Ctr once its full, and keep topped up from the Right Main? Suppose million ways of Skinning a cat!
