“fan-fan-fiction” seems wrong, that just denotes a fan of a fanfic (or perhaps a fic written by a fan of a fan).
I’m tempted to say fanficfic instead, since it’s a fic of a fanfic.
But really, fanficfanfic seems most accurate if you’re going to do something like that.
So might as well just go with “recursive fanfic” or “metafic” or something like that.
