Frontier, that's brilliant, and quite in line with where I thought they should have gone with it too.
Yeah. I've often thought of writing out a fan-fic "pilot" about how it would have been/should have been, but, I'm apathetic and lazy.
I certainly wouldn't have done the ship as Enterprise, though. The name I settled on was U.S.S. Pioneer, with a registry something like NCC-170. And so then, their main shuttle craft could be Shuttle 1, and so like in TOS, it would read NCC-170/1.
