[WhoDatNotSayin]

Already discussed on the SAS forum, where Sean2323 made the same suggestion at the same time. The link he gives is to a fantasy, though there was a single prototype K-7, which first flew in August 1933, but crashed due to structural failure later that year. Relevance to any combat ever likely to be featured in IL-2? Zero. If some modder wants to make one, fine, but hardly a priority....
