Deconstruction

I am attempting to create a fic where I can deconstruct a genre of anime specifically the mahou shoujo/magical girl genre. I had read Sailor Nothing and watched Mai Hime however I still feel as though I can use more research on the topic of magical girl or deconstruction. I am not trying to create another Watchmen or Evangelion, I am not really all too sure that I create something at that level but I seem to want to subvert, avert and and possibly invert quite a few tropes in the genre. How much research do I need on magical girls, deconstruction or just about any on storytelling? What would be a good idea for magical girl story that takes something and twists it? And do I need all that mind boggling symbolism that I find prevalent in such literature?
