I've been looking for a "blank" mechanical keyboard with cherry mx silent red switches — is it possible to add those to the options?

The Ergodox EZ can come with Red switches (both silent or not). It's also got hotswappable switches which is pretty cool IMO, you can change your switches whenever you want without having to desolder or even unscrew anything.

I can really recommend this keyboard if you find the Ergodox layout comfortable, they're very well built.
