Oh, I like that. Instead of going for high-speed as in the XF-84H, they go for lifting capability with the straight-winged F-84 as a start and mix in a touch of A2D. Now, if Allison could only get the engines right without having to go through a complete redesign or got the redesign done faster. These would be perfect with T54 engines (T54 is to the T56 as the XT40 was to the XT38 - i.e. two of the other's gas generators driving one gearbox).
