Hi,
I have gone through your post. Sounds quite interestng! Honestly, I can not change the color of your hair or eyes right now, but can tell you how possibly it can be done in the future, at least theoretically.
By the way, CRISPR CAS9 alone may not be enough. It can cut the gene precisely, but is not so efficient in case of targeted insertions. So, you may need additional tools such as 'Retrons' as well.
If you are interested, please leave me a message.
Best regards.
