I'll bow to anyone's greater knowledge but I'd have thought that the necessity for a lift fan engine inside very much the same size airframe and the need to supply fuel to that lift fan engine from inside the same airframe would impose some sort of limit on weight and available internal fuel? Even without the use of fuel to the lift fan for 'STOVL' performance, in addition to fuel for the normal engine, I'd have thought the lift fan is surely just along for the ride? But again, I seriously would admit to not really knowing????
