Might be interesting to have something like that towering in the base. But I can see some problems - for example, this design won't be able to glide down to earth from space and land without considerable help from some engines.
The idea is such that there will be thousands Colony Pods attached to the Mothership. The Mothership was meant to colonize other systems, visiting selected stars on its journey, deploying several tens or hundreds of these pods at each habitable planet or moon to increase chances of humanity survival. These pods are designed to land on the planet and root there. All energy will be handy for establishing the base, so these pods should not consume much fuel during the descent. Some of it will be needed for safe landing.
You may say that we don't have to adhere to these rules, but we want it to be logical. We are looking for designs that are reasonable, and not that far out to the future. Ie. the closest future when mankind could assemble a giant spaceship in orbit, freeze the the volunteers in cryogenic chambers and send the ship on a long journey from which it should not return.
