Very different I imagine, with different types of characters. The ring ship wouldn't be military, but it would have defences, because you never know when you might need a missile or two. Boaty McBoatface, in space. The mission might be tightly planned and intimately choreographed, much like the probes of today. A meticulous flight plan to visit carefully selected points of interest and rendezvous with homeward bound sister ships and deliver supplies to young colonies and outposts along the way. I haven't quite formulated what a typical episode might look like, beyond the setting, but I know what it isn't. Its not gung ho captain Hornblower stuff. Its not super beings testing humanity. I always remember Roddenberry saying 'Aliens didn't build the pyramids, human beings built the pyramids, because they're clever and they work hard' Or words to that effect. There is a gap in Trek lore, when humans were alone in the bigness of the universe, and they made enough of a mark to stamp their identity on a 150 worlds that became the federation. I'm working out the details on this one, but I think I could pull together a viable detailed series outline that fits existing continuity, offers something unique, and is genuinely compelling. I might even pitch it, if that's even possible these days, do they do that any more? Its fun either way.
