re: What would be the level of euphoria on here if Caleb Williams transferred in?

I would feel some ambivalence TBH. I like his potential upside but I don't think it is significantly better than what is in the QB room already. The only reason I wouldn't think "No thanks" is because we are unsure what Brennan brings when he returns (I am hopeful and cautiously optimistic), we really don't know what the offense will look like so Williams may fit the general framework better (honestly think BK will tweak the offense every year to optimize for the QB/WR/RB talent he has), and I think Caleb Williams looked better than Nuss in hos outings at OU.
