If we can achieve the nanotech capability that you describe........
well, that gives us God-like power to do almost anything!
So, I doubt whether that will be possible.
If it is possible, then reconstructing ourselves and our Solar System
will probably be first on the list.
Interstellar travel will be way down the to-do list, if ever.
Going nano may be too much fun.  :)
