Welcome to the Herd, Doc!
Do you have the HobbyBoss Kearsarge yet? You might need to see the kit, to decide how much aftermarket detailing you want to ad.
I have the HobbyBoss 1/700 Arizona kit, which I am converting to the Pennsylvania circa 1935. I was gung-ho for the project when I started, but over time, the soft detail and bad engineering of the kit soured me on it. It's been on my Shelf of Doom now for 10 years. I think I even have a thread here in the forum for it. I've resolved to finish it this year, but I've done all of the detailing work that I plan to, just adding PE rails. HobbyBoss can be very inconsistent, that is, some kits are awful, others are very nice.
The HB Arizona is a distant cousin to your kit, by the way. That's the old Revell kit, which was released back in the 1950s. It's been in their catalog ever since, in that original box scale (ie, engineered to fix in a box of specific size, not to a consistent scale), and scaled down to 1/720; and boxed as the Pennsylvania as well. I built them when I was a kid, enjoyed them thoroughly, back then.
I say it's a cousin, because back in the 70s, it was copied in the PRC and released by several iterations of state-sponsored model companies, including Banner, and the forerunner of Trumpeter. If you can find any of those releases, you can see the common engineering, such as the horizontal seams on the deck house and the superstructure decks, the way the fighting tops are molded, the way the hull is broken down.
Trumpeter's 1/200 scale kit is a completely new, different, original design, unrelated to that heritage.
I look forward to seeing your build, when you get started!
Best regards,
Brad
