Longest Brawl isn’t related to Subspace Emissary in any way. The key reason Longest Brawl came into existence was that I was always disappointed that Subspace Emissary never really had a coherent idea that allowed all of these wonderful characters to come together. They just sorta did.

What sets Longest Brawl apart is that we created an original story that allowed all of the different Nintendo worlds to come together and have an actual crossover, sort of on the level of The Avengers. Its very much an origin story.
