Looks like the F-111 may have inspired the B-1B design. I worked for Rockwell International on the B-1B production program and the F-111 was the chase plane used on the Maiden flight of ship 1 of the B-1B program.
The B1-A was very much like the F-111 in that both used much of the same avionics including the terrain follwing radar, and both had crew escape capsules rather than conventional ejection seats.
The production B1-B, however, dropped the crew capsule design and has conventional ejection seats.
The B1 does look like an up-scaled F-111 now that you mention it
