Curious to hear ideas for this windowsill.

It's on our outhouse in an area we're tidying up. The previous owners obviously scored a double glazed unit and installed with the wooden sill. I've discovered the brick sill below is the original and would have matched with the house.

I started to paint the sill and frame white (as I was using it elsewhere), and it's occurred to me that part of what makes it look so shit is that the green paint makes it look like spare paint was being used. Going to do the surround in black.

Uninstall/reinstalling is not an option. My two thoughts are:

1. Work out a way of cutting the wooden sill flush and blending it into the frame so you only see the brick sill. I have a circular saw, but doubt it'll get flush enough.
   
2. Build a bigger "fake sill" to merge the two together.
   
   

Any bright ideas?
