You're unlikely to find a good one because it's a bit of an odd item. Best bet could be to mill out a bit of a hub with a dremell or the like and put in your own switch, or 3d print a new case for the two, or just get separate ones that have a similar finish
Edit: or as other people have mentioned, you can get the whole front io panel of a case you like if it is detachable/available for retail or you can route it out of the entire front part of the case, I'm sure you can find something that looks nice this way too
