I got myself a Giro Rumble VR size EU 46/UK 11/US 12 and it has been a good shoe.
However, since they are very breathable, my feet are getting too cold at around 5 deg C, and I tried to get a regular road shoe cover for them, such as the dhb Extreme Weather Neoprene Overshoe.
But as can be seen from the photos, the Giro is basically as large as regular sneakers, and it was impossible to make the L-sized covers fit it, and I don't think XL would have been large enough either.
Is there any other cover I could get that would work better? Or do I have to just buy warmer/more standard sized MTB shoes?

I'm not in the mood for DIY (doing enough of that already), so I just got myself a standard sized dhb Dorica MTB Shoe and that worked with the cover. I got the non-extreme one though. This was an improvement, but it is still a bit cold when nearing zero. I might get a toe warmer as well at some point. The Giro will be reserved for 10 degrees +. One advantage of the Dorica is that it is easier to clean due to leather-like cover, especially when you can jus wash the cover separately.
