does aura of multiple Yato's stack?

If i have 3 Corrins with refined Yato on them, and he has ally support with Kana.. and then if Kana fights when she is being affected by 3 Yato's aura, will she get 12 (+1 or +2 from ally support) invisible stats bonus?
I have not many Dews, it is just my curiosity

The good thing is that ally support does not applied for arena defense team.. haha
