There are a couple of British types that need to be done and my guess is since TVAL has'em, I think we will too: 1. BE2c and BE2e. There are more differences between the two sub-types than their wing plans as described in the data files.
The other British type I would hope to see is the Sopwith Strutter in both English and French variants and 1 and 2 place configurations.
French types that I would like to see are the Voisin 3 and the Breguet 14B2 and 14A2. If anyone has seen Harry Woodman's excellent build of the Hi Tech kit, you will appreciate that the 14B2 has a lot of complexity and can be built with bottom viewing shutters open.
