No, she wouldn't. A mode is an enhanced state that lasts for a limited amount of time, the only one with SPASM is Naruto and Asura is presumed in the least.

The TT jinchuuriki get SPS from the Ten-Tails and it certainly uses no mode, Kaguya is the Ten-Tails, the power is baseline for her. Also she used a huge Truth Seeking Ball.
