I wouldn't worry about that figure 8 hole, if one is actually created. 5 lugs will hold the brakes just fine on similar weighted vehicles, adding one more hole isn't going to hurt a thing.

For more info, go to the library and look for books from the 70's on hot rods and customizing. VW books tended to have lots of how-to's on re-drilling hubs for different bolt patterns, and modifying junk yard parts to the bug chassis's.

First and foremost, have fun with the project!
