the code can only be split up into so many modules, for efficient coding eahc module can only really have 2-3 active coders, usually 3 gets to many, and most modules can't have more than 1, or they'll mess up for each other.
No, more people can't make assets faster or better. one guy can only make one asset, then handed over to the texture guy and animation guy where applicable.
Test people are actually rather irrelevant, at some point you will simply have to many of them and they become less useful more of a hindrance. and they're generally cheap, so you can easily have enough testers for MP and SP.
part of the teams are shard between the two, mostly the art teams. (getting back to this). the rest, no they can't really do anything useful that the people on the MP team don't already do better. they'd just be in the way.
As for the art thing. Art is actually the last thing they start working on in the game, and the first thing they finish. coding starts first, and coding+QnA+Debugging finishes. Art while it's the most visible part of the game is the fastest part to complete. Hence why artists will often switch to work on art assets for the other team during dev when needed. Hence more artists aren't useful, and they won't help. on top of that. On top of that if they where to make more levels. they'd run into other problems, first the players would have to many maps to chose from which would cause an issue with players being to spread out. and more importantly. the AnA for the maps take a lot longer than makign them, QnA also including debugging, balancing and bug checking.
