LOL! Again, your choices were so very different and that's what I liked. It caused me to stand back and think...Yea, I don’t know why, they just spoke to me lol. I “C” gives it a bit of a “starfighter” feel that for a freighter just limits the available(and already limited) usable viewing area.
The other two seem more “Falconish” or inspired and look like logical changes in models or updates maybe?
The "concept" ship I'm thinking will be a "YT-300" variant. It would have been built a good 50-100 years before the 1300. It's going to have very similar lines as the MF just very old. I'm coming up with a origin / back story for the ship now.
