I suppose you might could cut that portion out, capture the stitches of the pieces around it, repair them, and then knit a new section to replace the one you took out. HOWEVER, doing this would be tricky at best because you'd have to get the new piece the exact same size as the old piece, and I'm not at all sure how easily you could pick up and repair the cut stitches.
I know the blanket is finished, but what if you added some other "logs" that have been purled. That might be the easiest thing to do if you really think it has to be changed in some way.
On the other hand, it sounds very avant-garde. I would just leave it as it is, per GG's recommendation!
Another thought: Since you only have one log like this, perhaps you could add the baby's name here (via crochet or embroidery). That might make it look intentional, and it would certainly make it unique to that baby!
