A long, long time ago, I played with the notion of a direct scaled-down version of the B-1B as an F-111 replacement.
It used two instead of four F101 turbofans, crew of two, two weapons bays (instead of three). I'll attempt to find my paperwork (yes, it was so long ago, that it was pre PC days for me!

)
From memory it was just a smidgen larger and heavier than the F-111, but in essence, I think such a design would have been very effective in terms of cost, performance and capability! In essence it was a straight out mini-B-1B!
