The Romulans may be who we are supposed to empathise with in this series, whereas other Federation member species may see this as an opportunity to take revenge, or manipulate events to their advantage.
And rather than all the Romulans be on the same page regarding what happens next for themselves. We could explore other factions, and deep dive into the cultural diversity of the Romulan (and Reman) diaspora.
Give to the Romulans, what TNG era gave to the Klingons - more depth.
The Tal Shiar would be full of suspicion at the Federation's willingness to help, and so would be infiltrating Federation Council discussions. Other members of the Federation may seek to leave or protest over help being offered. Romulan colonies may provide an allegory to Migration fears and "problems" we are seeing across the world today.
Maybe even add in a Brexit like story with a planet choosing to leave the Federation because of a distrust of the Romulans.
There is a lot that could be done, if they went in a political storytelling direction (plenty of public speeches from Picard) and avoid flashy action scenes and effects shots, and focusing on characters over events.
