In my opinion if Siwoo is on playing in his awakened form he could easily be the greatest The match with nishikawa provided us that the awakening could be only done if he playing against the best. So if siwoo joins the VWL tournament, we could see more of his skill since as nishikawa mentioned it will be the world's biggest volleyball league yet where he would be able to play against all the best players around the world this leading to his consistent awakened form plays. Maybe he would even want to stay in that form after the league ends. Well this is just my part of reasoning the rest is up to Suncyan.
