Spaceception

I have a mod idea for later, when I get a new laptop, and learn more about programming.

I want to make a mod pack about "Ark". Both a parts pack, and planet pack, the parts pack is a generation ship, several times larger than say an SLS, with an Orion drive for takeoff, an Alcubierre drive for the star travel, and 4 shuttles for planetfall, so I'll need to make a new resource, antimatter, and make it possible to get around Jool (Laythe's becoming radioactive/volcanic, but still with water!) I didn't see anything in the book that said it needed exotic matter, so I might need to read it again (You guys should too, it's really good), it will be able to hold 80 Kerbal's initially, and 140 max, life  but now the planet packs: In the book there were 2 star systems they went too (Not saying why, read it) both with habitable planets, the first system, afaik has 2, maybe 3 planets, one rocky habitable planet, and too far out gas giants orbiting 82 eridani, about 20 ly away, the second system, is an unnamed red dwarf, 111 ly away, with I think 5 planets, with the innermost one being the habitable one, I'm also going to make a skybox, so the stars will be where they are irl.

What do you guys think, and any tips for when I start possibly next year?
