I don't think that they would move SPN to 8pm, it's just too gory. And Vampire Diaries seem very lovey-dovey to me on the other hand. But I could see VD at 8pm as a sort of vanilla supernatural series leading into hard-core Supernatural. I know that they don't usually place new shows at 8pm but I don't see any other show on the CW, that would fit it better... On the other hand, they put together Reaper and 90210 so... What do I know?
