I don't think he ever mentioned that he particularly wanted the new doctor to be Selar or a Vulcan.
Not in those interviews. IIRC, Tormé was quite open re alien race and even gender when the production team was debating the new CMO, but eventually he had to pick someone and those ideas coalesced as Selar of Vulcan in "The Schizoid Man". Tormé decided on female because he wanted an unrevealed relationship with Worf to unfold and that also meant the race he chose had to be capable of surviving Klingon courtship rituals and intercourse, and Vulcans were TOS aliens known for being able to present a patient with the cold, hard facts.
Tormé was probably a big Spock/Vulcan fan. His other big unfilmed script concept for TNG was a two-parter (pre-dating "Unification") featuring Ambassador Spock using the Guardian of Forever and encountering a TOS-movie era Spock.
