Hi mate, in a nut shell, yes and would be fairly straight forward to add a basic looking interior.
The rear of the hull could be easily drilled out with a Dremel tool. I was going to do it but lack the LCAC's to go inside. But you've got some and I feel a man of your modelling talents could do it.
The ROK has built a second ship - Marado I see, and I might buy a second Academy kit and do that one with the open well. We'll see!
I suggest you buy the Academy kit just to have a look! Down here it's cheaper to buy than a packet of cheap Cigs.
Thank you for the feedback.
