It may be difficult for humans to improve on nature. It may be easier for AIs. Keep in mind that the space explored by evolution is necessarily quite restricted, and very damaging entities would have been selected out if at all possible. What you can imagine based on the evolved structures you've seen may be more limited than you realize. In any case, my previous comments were intended jokingly, they weren't submissions to Methods in Molecular Biology.
