I agree, the F-105 from WoE is wonderful! I haven't got the WoV yet (haven't seen it for sale here in Europe), but I'm looking into ordering it online (I want to get that Vietnam terrain!). I also have the original Strike Fighters (SFP1).
But talking about the cockpits... It seems that the original SFP1 and WoV planes (LODs, cockpits and data files) are included within the WoE's ObjectData.cat file... So it's possible to have any add-on to use them if you want. I even managed to make the A-7, F-8 and A-6 flyable in WoE by downloading some third-party skins and creating appropriate folders and ini-files.
