I don't think so. Hanzee sided with Dodd over Floyd early in the season when he lied to her about the Butcher being a Kansas City hitman. He also hasn't been in contact with any of the Gerhardts since before they left to break Charlie out of prison. The main reason that Floyd would've turned on Dodd would be the attack on the Gerhardt compound as a result of the war that Dodd started (which went against Floyd's orders), and that happened while they were at the prison. Even after all that, Floyd was actively looking for Dodd trying to make sure that her remaining family was safe. If anyone was to turn on Dodd, it would be Bear, but we've seen in previous episodes that Hanzee was loyal to Dodd over Bear. As to the end of the war, Floyd already promised to turn control over to Dodd after the Kansas City situation was resolved. She wanted to guide the family through that ordeal because she thought that was best and that Dodd would be a poor leader under those circumstances (which he proved by provoking the war and getting people killed). I don't think she planned on running the family long term, and I really doubt she was willing to go to war with her son over control over the family.
