Should Yuehua add a korean member to replace Yiren?

As much as I hope her to come back, I fear with what we have seen in the past of how Yuehua manage their chinese idols(WJSN), I think Yiren now will embark on a new career in China. So should they for example recruit Lee Sian from Produce 48? The girl has been wandering without any plans for debut since the days of Pd48. She did Rumor with Sihyeon.
