Dear Crosser-Over(er): Crossovering 2016

As a confirmed crossover geek, this is rapidly becoming my favorite annual exchange, even if it is the most complicated. And as always, I am even more than usually grateful and impressed with whatever crossover ends up coming my way as a result. I remain in awe of the folk running this particular venture, because I suspect the matching -- even with AO3's automated engine in play -- is more than usually interesting. Thank you very much for volunteering for this madness, and specifically for your willingness to indulge my particular cross-fannish sensibilities.

Anyhow. Per the usual form of these things, here's a cut, because this is going to be even longer than usual.
