Not an update in this post. But based on the newly obtained top view schematic of the studio model released by Kuhn, I find my "eyeballed" model to be amazingly faithful to the original
In the image below, the original studio model is in grey, and my mesh is outlined in bold black. As you can see, only the midsection and engine section needs to be adjusted, and that only takes a few mouse clicks since I haven't started to add any detail to those sections yet. A slight adjustment of the landing bay is also needed. This new info came at just the right time
as having to modify a model after millions of polys are model is a major pain in the arse. All in all, at least I know that my sizing technique is confirmed valid and I'm on the right track!
