It's fun to set it up, and eventually we hope to get the Deferi some more recognition (you can see our "mission" under the "fleet" tab). Or they will ever be a selectable race is doubtful, because Deferi are not a canonical race, but made up withing the realm of STO. But we do have our own visitable planet (which we hope will be enhanced). And surely the Romulans should have a visitable planet too, that should be your objective, I think. To get a group of Romulans together to petition Cryptic to create this.
A Romulan zone to visit, a Romulan selectable race, that could be your mission. And Romulan lore does not need to be created, there is plenty information available to gather for your website.
