Would you be happy with this..

Going the more fiscally responsible (and perhaps riskier) route, by offering Kirby Smart 3 Million and the head coaching job, Tyson Helton (Western Kentucky OC) 500k for OC (almost 5x his current salary), Promote O to DC (you've got a proven DC at head coach so that transition should be easy and it would also help retain the recruiting class) with a raise (maybe 1 mil).
So you're looking at something like a 2 million per year drop in administrative costs.
That should give you some money to either throw at Frank or hire a decent replacement.
