When I first read this, I thought you were joking. Then I realised you weren't, so I read it again and looked more carefully at the headstock. It's a really neat idea! 👍
What might also work instead would be to run a parallel scratch also from the top of the headstock, exactly the same length, pointing to the 3rd string hole. The current one points exactly to 5th. The two lines would then frame the bau logo and match.
