Hardmode Kerbolsystem (RRS cfg) - Specific Ideas ?

[thyriel]

After i worked the last days on the "kerbin sized rss config" (real solar system) i thought gameplay wise it would be fun making a config that basically has the same planets / moons like stock game, but moved to a lot harder to reach positions (aka fantasy solar system).

Things like planets orbiting in the opposite direction, extreme eccentricity, probably could even work raising mountains and adding an extreme thick atmosphere so you can only land on mountain tops... maybe a different starting condition on Kerbin then 1G and normal atmosphere...

So what do you think ? Would that interest someone beside me playing a crazy solar system for fun ? What are the kind of planets, moons, specific orbits, or even sun parameters you always thought that would be cool to try out ?
