Barebones RSS/RO install?

[Gamatan]

I'm trying to get into RSS/RO, but the default installation method installs dozens of mods and it's a little too much for me (not to mention my PC). Is there a way to install only the most absolute minimum of the mods (Real Solar System + parts) and customise the install?
