Genetic engineering of the human genome is a difficult and slow process
Designing one new gene would be far beyond our capabilities. But choosing a set of good alleles based on genome-wide association studies would be trivial. Combining them together in a gamete would be difficult with current technology, but may become easy quickly. GM crops exist with IIRC at least 6 stable transgenes.
