The Emiya faction (No story just an idea)

There have been many fanfics of Fate Apocrypha getting a third faction labeled "the faction of Blue" most of the time consisting of the Fate/Stay night servants (or that one Dark souls fanfic which called them the faction of Ash/Grey) but what if the new faction of Blue (for convenience's sake) was made up entirely of various variants (most are from fanfics I read only 1 is canon) of Shirou Emiya.
