Koei itself related a "Samurai Warriors 4 II", which was basically Extreme Legends without the combination function. It might be their standard mode of operation now since Capcom sued them claiming to have patents for disc based expansions/combination of games on consoles.
Extreme legends games usually add a fair few characters and stages sw4 ii only adds one character and I don't believe as much content either so I'm not really comfortable saying sw4 ii is like a main warriors game plus xl
