Masdevallia zahlbrudeneri is a warm grower and I think? lower light so should be good. The Scaphs are all very neat. Your temp range should be okay for most of them including Scaph breve. Have you checked out Scaph erinaceum/Masdevallia erinacea? IOSPE PHOTOS
(Btw, not to be a pain or anything, just an FYI ... the species name is never capitalized.)
