Let me start by stating that I wouldn't want to see this happen. But...
A logical way to dig themselves out of this hole -- ignoring the fact that digging yourself out of a hole is the absolutely wrong approach to any problem -- would be to cut a management deal with KQED to run the stations for them under contract.
KQED already has a presence in Sacramento (KQEI in North Highlands, which simulcasts KQED-FM 24-7), and much of the programming already airs in parallel on the Cap Radio and KQED stations. (12.5 hours are totally simulcast, and another 3.5 hours of content are just the same programs airing at slightly different times on the schedules. Weekends are more different.)
So merging the two news operations, en masse, with just local news and underwriting inserts customized by region, should be doable with a whole lot fewer people and operating budget than the current situation. And heaven knows KQED already has more headcount than they need for what they do.
The downtown buildings are going to have to get sold or subleased soon anyway. Cap Radio headcount, sadly, will need to be reduced even further. The only local daytime hour they produce in house (Insight with Vicky Gonzones) might be a goner in favor of KQED's Forum, or at least folded into that organization. And since the transmitter relocation project is nearly complete, that's a sunk cost that will hopefully pay off with improved listenership and better fundraising. The classical music operation may need to be subcontracted out to USC's California Classical, which already runs the KDFC stations in the SFBA. Making these changes might jump-start the effort to get the house back in fiscal order, albeit at the expense of the local flavor. (Which listeners in Tahoe/Reno, Quincy, Stockton, Sutter, Chico, etc. might not see as their local flavor, even now.)
Maybe, five years down the road, Sac State could consider taking back the operation. Or they might decide they don't really need to be in the business anymore of operating a network of stations, and leave things in place. Who knows? A lot has happened in the last five years, no reason to believe things won't be even more different then.
