For campaign mode wouldn't it be a workable first step to:
1. add habitat and supply modules as available parts
2. make placements on the various planets permanent
3. allow rebuilding/consolidating parts and fuel on the various planets to create/launch new rockets from there.
With just the above we could build and supply a Smoon base, ferry raw materials/parts to it, build new rockets at it, launch them from the lower gravity well there to the other inner planets, then even on to the outer planets.
The competition on the leaderboard to build/supply the largest base on Smeptune would be intense.
