Ideally, you would have the ability to re-start with the experience you have accumulated,
the equipment your colonists wear, the science you re-searched, your trained animals and
maybe even a small wagon with selected ( limited to one 10x10 stockpile or so ) goods and wares.
What interests me personally is re-settling in a totally different biome,
either upping the difficulty ( temperate -> arctic ) or the other way round ( desert -> temperate ).
You partially could do something like that with the prepare carefully mod,
but it would require quite some work and all science still would be lost.
