The great thing about ball joints is they are spherical bearings and the shaft direction does not affect the axis about which they pivot. I agree that having the shafts point toward each other is good practice as it allows for a wider range of motion, however as long as the ball joint is not the limiting factor in steering, compression, or droop, the shaft angle doesn't hurt.

I am not against using Mustang II spindles to reach a different compromise, but I don't consider our original design as being flawed, it has worked very well in the spec racers running in the main NASA race groups.
