I have two suggestions.
Suggestion #1 - Have a cold open before the opening credits, and have that scene be the one from the Mandalore when Ahsoka fights and captures Morgan. Even if it’s edited down, having that scene I think would be an awesome introduction to the series, action-packed, who Ahsoka is, who Morgan is, her power before… PLUS, it creates a fabulous full-circle moment in the end when Ahsoka and Morgan are fighting on the top of the fortress.
Suggestion #2 - The title you’ve chosen is quite generic and lacks punch. I’d workshop something else. It just doesn’t hit or sell really what this is about. This is a story about a journey of rebirth, discovery of self, and a dangerous return with a dash of hope (Hi, Ezra!). “A Threat From Beyond,” I just don’t feel captures that at all. JMO.
Anyhoo, looking forward to the finished result.
