I want to get rid of the 40 freaking wires at the bottom, the only way to do this is to use thinner traces. Making it double-sided wouldn't help, the pads are in the way on both sides.

I need to find out if this trace-width is acceptable for this board, the image below shows a rough idea of what i want. Normally i'm very strickt with 45 degrees angles, but in this case it's not really doable so i'm making the exception.
