I do think so. There are still many question marks in One Piece (a few of them could be the same thing):
- The Man with the Burn Scar;
- The rest of the Roger Pirates (Gaban especially);
- Elbaf;
- God Valley, Rocks and the possible remnants of his crew (e.g.: Shiki);
- Imu, the Gorosei, the God's Knights and the whole WG plot.
And so on...
The eyepatch pirate is probably related to one or more of these things.
