I've seen plenty of fan fictions that star Emiya Shirou, but works that star EMIYA Archer, or Counter Guardian EMIYA, are far rarer to find, especially if you're looking for one that isn't abandoned. Keeping this in mind, I feel as though I've seen crossovers with EMIYA go far more interesting places than the regular fan fictions, though both have their own appeal. That said, how can you have the best crossover imaginable starring EMIYA Archer? By making it a multiversal fan fiction; I'd also, yet again, prefer for there to be a foothold in the DxD world, as well. I personally prefer Counter Guardian EMIYA over Emiya Shirou, so I always find myself wishing that he got more spotlight outside of the main series of Fate/Stay Night, because even there he only really had a small moment of focus in the Fate route, a clash of ideals in the Unlimited Blade Works route, and him actually being useful heroically in the Heaven's Feel route. The clash of ideals was nice, but that and small cameos such as when he shoots Gilgamesh or his farewell to Rin don't really give him enough spotlight for my liking. The small moment of focus in the Fate route definitely didn't do him justice, and I don't really have anything bad to say about his portrayal in Heaven's Feel. Outside of Fate/ Stay Night, can you imagine him in Fate/ Zero? Some people have already done it, but there's a lot of potential there. There's one place with even more potential, however, that being Fate/ Grand Order. I was quite annoyed by the fact that he's just one of many servants in Fate/ Grand Order and that's he's not involved in the plot other than Fuyuki. I'm not saying he needs to be ranked up to a five star servant, no, because he isn't really powerful enough to be a five star and even being a four star is kind of pushing it. What I am saying is that Heaven's Feel is the closest we get to Archer actually supporting the main character or being the main character himself. In Fate/ Grand Order, while I understand the intent to branch out to other historical figures and myths, not focusing on reality marbles and Emiya Shirou, it would have been a prime opportunity for Archer to have his redemption for his Counter Guardian duties. I just can't help but feel like it's a wasted opportunity, so I'd be happy if someone made another fan fiction doing that, or even just displaying his life at Chaldea without him being involved heavily in the main plot.
