Thank you for the replies. Boy, it's hard to please everyone

. Make it in full flat grind, put the lock on the other side, move the clip for tip up carry... Fortunately, the grider was still warmed up

and here's the result:
Now, a disclaimer. I made the knife just to see if it can be done and how would it look like. Because the knife should retain the Sebenza look while bearing in the same time the distinctive spyderco features (comp lock, round hole), I had to deal with some pretty severe restrictions. I think there is still a lot of room for improvements in this knife, especially regarding the ergonomics. Honestly, it is not the first knife I'd pick myself as an EDC. But it looks acceptably nice and it was fun to work at it. :)
As always, you were great with your comments and feedback. Thank you for the joy.
