I always liked the notion of a half-scaled Rockwell B-1B as a replacement for the adhoc series of General Dynamics F-111 series - with two crew, instead of four; two F101 turbofans instead of four; two internal weapons, instead of three.....
I'm assumising that by utilising the principle of a half-scaled B-1B, so much money would be saved in R&D, while mitigating development risk, because it had all been developed and proven in the B-1B program itself, which one would think would naturally equate to massive economic savings and a quick and fluid OIC.
