I think, if they haven't already been established as working as a team squad outside of Smash, they have no real business doing that in Smash.
There are certain examples of characters in fighting games where this works (TMNT in Injustice 2, Captain Commando in MVC1 and 2, Phoenix Wright in MVC3), but this is because their lore already established them as working together to achieve mutual goals. If they didn't already have that established tight-knit "team" aspect to them then it would make about as much sense as Mario summoning other characters from his series for his moveset. Why not just make him pull out Toad and ride Yoshi instead of making them full fighters on their own? The reason why this isn't a good idea should be self-evident.
