No, no additions like you ask. The two version are "mostly" compatible, but there are those pesky airplanes that are not, hence you have to start a new career. There are a few mission out of Brisbane and a couple out of Fremantle that might cause issues, but then there are a few issues with v1.004a also, so in that regard, they're about as wide as they are long. I would finish the career you are running now. For the most part, the torpedoes do not cost any less, but the Mark10 will be available part of the early war for the fleetboats, at a renown cost also. The S-Boats start with the 4" guns, and go to the 3" ones, giving their 4" guns to the fleetboats. Little things like that.
