Not on a TV budget, and what about their voices?
Wrath of Khan, The Search for Spock and The Voyage Home are in different realities then according to those guidelines.
I'm sure there are other examples.
Well they did it quite well for Trials and Tribbleations on DS9 so I'm sure they could do Spock and a few of the others just for a few scenes and dub Nimoy's voice from TOS!
Wrath of Khan and the other two are in different realities? Is that because of Kirstie Allie's Saavik? Well I can't answer that one but maybe Vulcans have the ability to alter their physical appearance to a lesser degree? I mean the woman that played T'Pau in ENT looked nothing like Celia Lovsky in Amok time!
