When I first saw this cover a month ago, Shran does look like hes in a Starfleet uniform. Would be interesting to finally see him on the Enterprise, even if its to help out with the War.
Lord knows the series left him in a position to be available, a captain without a ship. I could see an office exchange program with the Andorians, like Vulcan's with Starfleet. Didn't Shran say he was likely to face retribution for losing his ship? Demotion to Commander or its Andorian Navy equivilant, and assignment to Archer's team... make him Starfleet's problem. Might be interesting.
