Well if you’re gonna do that, you might as well have it accompany a star to give it energy for that journey. Add a gas giant or two (or 4) to protect it against incoming space debris and help stabilize orbits. Add some neighboring rocks to also help with that + give them extra material to use once they arrive. Implant ideas of leaving the rock and coming from a place of great power into the colony’s generational memory. Include some infrastructure to aid them.
