Get muzzles. Keep doing OB together, structured walks together, and off leash walks with one on leash and the other off, then rotate.
In the house when you are working on intros, muzzles need to be worn, along with corrective collars and tabs. Dogs should not fight unless allowed to do so from the leader, so if you say behave they need to. Now of course, they are going to blow you off and try to start something. Which means you need to be right there to redirect and correct. IMO, going after another dog in my house is a HUGE sign of disrespect and is not tolerated.
In between sessions, or when you are not directly supervising, crate and rotate. They will most likely never be trustworthy together without you there, but it is not unrealistic to expect them to behave in your presence.
