I know some problems are known, like bone mass, however. Some science fiction books have distant-future human descendents who genetically engineered their whole family lines to be specifically stronger in zero-gravity situations. I imagine that might be possible in the future, but that always gets into ethical situations to me with a sort of "space master race".
That doesn't sound like much of an ethical situation. Some people will use genetic engineering and technological augmentation to adapt themselves to their new environment. If somebody wants to stubbornly stay "pure" for religious or personal reasons that's their choice but we can't hold everyone else back because there's a couple of stragglers, metaphorically speaking.
