I'm thinking low cost veteran.
They have Schneider and Biggio and Orelvis/Barger/Clement/Palmegiani. I am thinking they line up with some veteran at 3B and Schneider at 2B, with Biggio being a possible platoon partner for both if they don't hit. If Biggio performs he could steal a starting role at either spot. Then Orelvis/Barger/Palmegiani as MiLB infield depth. I'd prefer if Espinal is just thought of as a backup SS and nothing more...
These guys are ugly options but as a one year stop gap on the cheap, maybe they would be fine (2023 WAR):
Brian Anderson (0.5), Giovanny Urshela (0.4), Evan Longoria (0), Donaldson (0.2), Tim Anderson (-0.4), IKF (0.3), Amed Rosario (0.2), Brandon Crawford (0.6), Donovan Solano (1.1)
I mean there is nothing in free agency so the only other option is a trade. There are few trade options though, if you think realistic and only focus on minor moves like 2025 free agents. Brandon Drury? He's a good f***ing target tbh.
