No, but maybe close.
A777 200LR or 777F would be better.
Still, you are talking at least 40 hours endurance (probably 50), which would be 300-400 tonnes of fuel.
A VERY optimistic DOW would be 120T, so a BRW of AT LEAST circa 420 tonnes- 70T over MTOW.
But, yeah, experimental category it would fly at that.
