It could, but it'd be a mess. Personally, I'd stick just one post into Unlikely Crossovers - either this post, or post #1286513 (I mean, c'mon, the Hidamari Sketch cast with Ryukfaces, how much more of an Unlikely Crossover example can you get?) - and it can serve as a guidepost to link Unlikely Crossover fans to this pool.
