As someone with a background in biomedical engineering, who once planned to research the development of gene therapies for cancer treatments: yes, definitely :)

But we do know the basics, and our ability to synthesize, excise, and replace specific genetic sequences is quite sophisticated nowadays. So while there is some technical consideration regarding implementation details, the bigger barrier to gene editing experiments is the ethics. For instance, I mentioned FOXP2, and as it turns out, we've already done the experiments of engineering mice with human FOXP2 genes (which is how we learned that, in addition to language, it's quite important in spatial awareness).

While modifying a chimp comes with its own technical considerations, we've already modified monkeys in 2001 and then again in 2014, and FOXP2 is more compatible with chimps than mice, so... it's really far more about the ethics of such a thing.

Now, I was joking in my comment, but part of me absolutely would love to say "screw the anthropocentric ethics, as long as you're not hurting anyone, MAKE THE CHIMP SMARTER!" :D
