My apologies for the delay in responding here.

First off, for (big) Mikuru, unfortunately we don't think we can allow that in this case.

For the second matter, could you clarify just how the canon is different, and just what kind of medium it is? We do allow canonical AUs, we just need to get an idea of where they're from and how different they are before we can tell if they're different enough to be allowed in.
