Could Remain tell a better story?

Been thinking about how #brexit debate seems to be primarily emotional and not really built on data (or at least reliable data points seem hard to agree on). Wondering what it would take for those who want to #remain to create a brand or a business design planning output that described the narrative of why we would want to remain part of the EU. What would happen if we put our heads together in front of a whiteboard for a half a day next week? Could we uncover the right #strongertogether narrative? (and why isn’t that particular story resonating?)
