#3 Vanessa Borne's WWE main roster call-up
To me, the person from NXT that makes the most sense is Vanessa Borne. She's been off of TV since the start of 2020 and we haven't heard from her in any capacity relating to WWE either. Borne might be one of the ladies under the hoods of RETRIBUTION and that could be a way to introduce her to the main roster.
However, it would make tons of sense for Borne to be the woman in the SmackDown vignette. Alongside Aliyah, Borne's whole run in NXT involved a feeling of being better than all of the other women on the roster. She dressed luxuriously and was nicknamed 'The Vision'. That seems to fit with the brief look we got at the mystery woman.
She and Aliyah also called themselves 'highers' in reference to the rest of the women in WWE and NXT. Her bio on Twitter mentions the following - "I am Art. I am Culture. I am Eccentric Glamour." With the recent changes on Friday nights surrounding Bayley, Banks, Alexa Bliss and Nikki Cross, there seems to be an upcoming arrival of someone obsessed with glamour.
That sure seems like a perfect WWE character for the former Phoenix Suns' dancer. It would also give the SmackDown roster a different type of persona than it currently already has.
