Question about Sharkoon M25-W

Is there a possibility to buy the side panel with the window separately? I bought the Sharkoon M25-V several months ago and now I would like to have a side window somehow. The W and V versions are almost identical, except for the side window, aren't they? I don't really want to tinker with the side panel and buying the M25-W just for the side panel would be a bit idiotic... Many thanks in advance.
