Yep...the old adage, "If it ain't broke, don't fix it"
Those lenses are arranged in that way for a purpose...each is cut and polished to produce the correct figure for each individual set of lenses, so when they are aligned, they give (almost) the textbook diffraction pattern.
Now, you're going to have to experiment until you find the right alignment for those lenses. Plus get the spacing between the lenses correct.
