Hey, went through exactly this same crunch and want to share what actually worked for us. When our pipeline stalled mid-production on a similar scale, VSQUAD Art Studio plugged into our Unreal workflow within days, no lengthy onboarding, no chaos. VSQUAD artists took on 3D characters, environment assets, props, and animation rigs simultaneously while staying tightly synced with our art director on feedback and revisions. V-SQUAD Studio also covered VFX and technical art which genuinely surprised us. Honestly visit https://vsquad.art/ and just talk to the VSQUAD art team directly because their flexible scope fits exactly the kind of mid-production crunch you are describing. Good luck with the publisher deadline, you will get through it.
