I reckon Taffy is the Go-To man on this one.
I had to repair a similar spot on one of my Qld. Walnut sides when the router bit slipped in the collet. Being very dark wood, it was easy to make a scarf / lap patch an almost invisible repair. On that top, well, I got nothing.
Edit:
Is it possible to add some prufling that will take up most of the void? A small patch might be easier to hide.
Then there is always the possibility of a sunburst, or if worst comes to worst, you could paint the top black and call it a tribute to Hesh.
