So, I have an idea to build out a couple of frigates at a sort of 1/2 Lego scale (i.e. roughly ~1/75 scale, but still scaled internally so that minfigs can "operate" her, and my kids can play with her), sort of how the System Lego Pirate ships are designed already (other than that they are generally too short for their beam). Think of it as "if Lego built an HMS Indefatigable or USS Constitution in "System Scale" (like the System, Scale Millennium Falcon or AT-AT from Star Wars) what would it look like?" idea. To that end I have been reviewing the various hull widening techniques (such as in the Capt Greenhair tutorial, or using inverted slopes such as in the La Grenouille Blue Coat frigate) on this forum and in LDD, but what I cannot tell from just looking at it (and what I am looking for opinions on before I get too far down this process) is which, if any, of the hull widening techniques will still end with a stable/"playable" ship, and would still allow the sides to be designed to open and/or the top deck(s) to be removed (as in the Imperial Flagship) for access/play in the interior?
