I think it's more of a problem of getting permission from the owners. I've been working on doing some meshes for my own vision of TTM24, but my coding skills are amateur, so I'm happy to just work on meshes for now. As much as I like the originals, I think they need to be updated to reflect less Colliers and more reality. Don't get me wrong, the world of Colliers instilled in me the romantic notion of future spaceflight, so the whole idea in near and dear to me.
And, the Vespucci, whew! I thought that it was pretty cool to arrive in Saturn's orbit with more fuel than when I left LEO. I'd done a repaint of it to be a hospital ship (USNS Mercy). If I can find it I'll post it.
