Reminds me of this project: https://github.com/trichner/gitc0ffee which is used to take a commit, append some header to it to force the hash to collide with some prefix, such as `c0ffee`

>6 character prefix: less than a second

>8 character prefix: in the order of one or more minutes

No affiliation with this, but I tested it, and it was fast!
