I loaded the image into photoshop and drew some lines along the two edges of the fretboard to see where they ended up in comparison to the bridge pickup. There may be a slight bias towards the bass side, but if there is, it's not huge. You shouldn't have a problem with the neck pickup and the bridge can be located to match the neck angle. So it's just the bridge pickup that might be slightly out.

If necessary, you should be able to enlarge the cut-out slightly so that you can locate the pickup so the pole pieces are directly under the strings. If you are fitting the silver pickup cover over the strings, then you won't notice it at all. If not, then you may need to be a bit neater with any enlargement so that it looks symmetrical, but it should be relatively easy to do with a small drum sander on a Dremel for the round fixing lug areas, and a small chisel for the square end of the cavity.

Do not lose hope!
