Given the engines, it would've been unsuccessful, anyway. The Allison XT40 was the ruin of a number of otherwise good aircraft (Convair Tradewinds, NAA TurboSavage. Douglas Shyshark, etc.) and was two gas generators of the similarly unsuccessful XT38 driving a common gearbox. The XT38 went through a complete re-design to become the T56 and a corresponding development of the XT40 was proposed as the T54 but never built.

The overall description sounds roughly like a XB-55 derivative with only one engine pod on each side.
