  1. At one point, the talk was of switching from 8 small engines to 4 large ones, instead of the 1-for-1 replacement with 8 mid-sized jets.

  2. ​ @offshoretomorrow3346  The 747-100's JT9D and the C-5's TF39 were both given their initial flight testing via a JB-52E, in each case replacing the inner starboard pair with a single larger engine. You're right that this wouldn't have worked for the outboard engines because of ground clearance issues. Boeing at one point suggested replacing each pair of TF33s on the B-52H with a single PW2000 (as used on the C-17), which isn't as large as the TF39 and JT9D. But it still would've required significant changes to the wings to have enough ground clearance for the outboard engines, which is why it never happened.
