I don't know if it's too late to implement this @janman but it's always bugged me personally that the Armed and Rangerous cover art isn't square and looks a bit odd in my podcast app of choice (and I don't blame anyone for that except myself for being a perfectionist) so I made a square version for myself that I thought I'd pass along just in case you ever wanted to update it.
Totally understand if this isn't a priority for you or even worthy of your time, but it's here anyway just in case it saves you 15 minutes of trivial photoshop work (you might be able to do a cleaner version with the original file but Photoshop's content-aware fill did some heavy lifting here and looks about right). It's also here for anyone else who might have wanted a square version.
Keep up the great work on the podcast and your contributions to the site as a whole, love your work.
