Wicked is basically a deconstruction of alignment. The plot is based around multiple characters actively changing from good to evil, lawful to chaotic, vice versa, sometimes multiple times, all in circles around other characters. Trying to re-assign D&D alignments to Wicked is like smashing a vase so you call glue it back together.
I suppose if you really wanted, the best you could manage is to track alignments (and how they change) over time. But if you haven't read the book or seen the play, you'll really want to see part 2 first. A couple characters may not play out how you would expect.
