Is this unrealistic? On like a 120 stud scale, crew of like 8?

I would only do it if I figured out a really good technique to get the curves right. I was thinking two things: the new technic curved plates, and/or the use of swivel-hinges, which might look too messy. I could also just do it in rounded rectangles, but tiered. like steps, only less dramatic and with bley between levels.
The way the curves look on Mon Calamari cruisers, it's sweet. I don't mind a smooth hull rather than bumpy, but I would love to use my first SHIP as an opportunity to think outside the boxiness.
If I can get one really big, curved hull piece as the belly of the ship, I know exactly how to get the curves right on the 2-4 levels over or under it, like the first picture. It's just that first shape I have a struggle with...
Thanks for any input or advice!
P.S. The plan is to work in white, tan, and navy blue
