I don't want a really easy challenge, but not super hard, like SLS or Saturn V, I want an intermediate-difficulty challenge for me to recreate. Comment your opinions

There are many I can give, early Atlas, there are the Titans family, then there are the early Thor-Delta. Scout might be good too since its a thin rocket.
The only idea I do have in mind
Atlas V?
Good point...
Juno 1 or Vanguard.
Juno I or Vanguard are good. He'll have to make the smaller solid rocket stages for 2-4 stages for Juno I.
