The only way for the Queen Lancer to become her summon is if her fight against it leads to her "moving past who she was". Basically, the fight has to lead to some form of character development. According to Winter, anyway.

Defeating the Arma Gigas opened the door for her to finally get away from home, go to Beacon, and start learning about herself and growing without the constant pressure that she felt at home.

During the Boarbatusk fight, she snapped at Ruby, which caused Ruby to confront her about it in the hallway, and that led to Weiss storming off to Port, where she ended up being convinced to stop being pissy about Ruby being leader and start trying to be a great teammate. The fight with the Boarbatusk did kinda cause that. She was having trouble against it and was getting frustrated, and Ruby gave her helpful advice, which pissed her off.
