General Question regarding Dragalia Lost cheat in co-op?

[MarvelousKnight 0]

Has anyone use a Dragalia Lost alt account to carry their main one across HDTs. Like doing private raids to beat them or the main account joining the alt one and then opening it from private to public, other option is doing them solo since I have the might. I was thinking of doing consecutive runs on two trials to forge a HD weapon. I know my alt account using the cheat will get banned but I’m wondering if my main one will get the ban hammer as well.
 

I have been thinking about doing this and have been asking around but no one has answered this.
