Re: Reserved (this time, posting for me), and crap, how did I not say...
I could possibly write the minor/minor next-gen characters, though not as young schoolkids fucking--chan unwillingness still applies.
And, the person writing for me can: --go AU insofar as ignoring the epilogue if they want, or include it. I'd rather it were DH canon compliant, though if you, for instance, come up with some brilliant AU jumping-off point in chapter 3 of DH, okay, though sell it to me, yeah? --go AU in the pastiche/whole other universe/crossover way. I like AUs, but in this case I want two things: magic to remain fundamentally intact, and, family/relationships to also--that is, you can't bring Charlie into another verse but not Bill, Percy, the twins, etc.
If you need to know something about what fandoms you could cross/pastiche with, if you're having a notion of going there, you can always ask. Anon looks to be enabled here. :)
