Sure. One popular piece might be 'The Galactic Crusade in the 40k Universe'. It combines the epic scale of Warhammer 40k with the unique elements of Star Wars, like having Space Marines encounter Jedi. Another could be 'When the Force Meets the Warp', which explores how the powers of the Force interact with the chaos of the Warp in a really interesting way.
There's a fanfiction called 'A Star Wars Hero in the Warhammer 40k Galaxy'. In this one, a Star Wars character gets transported to the dark and gritty Warhammer 40k universe and has to adapt to survive. It's a great read as it shows the contrast between the two universes. Also, 'Warhammer 40k and Star Wars: The Crossover' is quite good. It details a war between the two universes' factions, with some very creative battle scenes.
Well, I've heard of 'Jedi in the 41st Millennium'. It imagines what would happen if Jedi were to exist in the Warhammer 40k setting. How would they deal with the constant warfare and the chaos? It makes for a really fascinating exploration. And then there's 'Star Wars Tech in Warhammer 40k', which looks at how Star Wars technology would fare in the Warhammer 40k universe, and how it might change the balance of power.
