The suggestions that I gave in details are just that -- suggestions. You don't need to follow them if another idea hits you. I'm really not that fussy. The most important thing is that you write a story that you enjoy and that you're happy with. I mean that. If you're happy, I'm happy.
As for me, while I'm 0 for 3 in getting assigned the fandom I hope for every year (next year for sure!), I'm very happy with the assignment I got. Time to start swotting up the canon. Whee!
