I don't know on what basis you reduced the number of first and second stage engines, but yeah, if you removed stages four and five, replaced the kerosene with a mix of RP1 and LH2, and changed out the 3rd stage engines, maybe the entire stack would be so much lighter that you could reduce the number of first stage engines.
What you really need to do is swap out the first stage for an S-IC. Then all you really need to do is swap out the second stage for an S-II. Finally, swap out the third stage for an S-IV.That should work fine.
OT but I would like to see an R-7 ICBM displayed next to an Atlas or Titan 1 ICBM.
IIRC, Korolev went with spherical tanks because Soviet companies weren't up to making non-spherical ones.
Yes, it seems that WWII Germany and USSR had/have design limits due to rail transport.
Hey, I had a teacher way way back in high school that use to comment, this country's long term future was as the bread basket to the world. The farm land is the one thing we have that can not be duplicated overseas by cheaper labor.
