The problem with that, I think, is that Gen2 LODs cannot be extracted from the ObjectData CAT file (ObjectData026.CAT for these carriers), and unless you can extract them I don't think you can hex-edit them. Unless, of course, someone has worked out how to find and then hex-edit the CV-63 LOD inside the CAT file, without extracting the LOD, but that risks screwing up the entire CAT file, which has a heap of other ships and aircraft in it.
Alternatively, if you have SF1 (Gen1) you could extract the CV-63 LOD and use it instead of the Gen2 version - it has a bare deck, with no Sea Kings on it.
