Do you think those keys would fit into a KBParadise V60 with Matias switches? I don't own one but I am interested in Matias or Alps sometime in the future.
As chyros just mentioned matias switches are pin compatible with older alps switches. There are a few exceptions, most notably SMK mount of which monterey blues are the most famous, but for the most part you're pretty safe with old alps boards.
In this specific case these Black ALPS are compatible, however if you're just after the switches you can get an AT101W for cheaper than this black model as it is rarer than the beige version of the same keyboard.
As for keycaps, I'd have to look closer but I doubt they'd cover the V60 properly.
I know they use the same mount
. But I have no idea what the keyboard is you're referring to - I know nothing about modern keyboards xD .
And just like some scotch drinkers, chryos only types on keyboards that could legally drink
