You don't want Utah. BYU will dominate the tv market with or without Utah. If Utah stays p12 then 33% of their fans join
BYU's fan base within 4 years.
You get no unique eyeballs by adding Utah. The Pac12 figured this out years ago when they decided not to add BYU. The SLC/Provo area just isn't large enough to justify 2 teams.
