No, it isn’t possible, because the premise doesn’t hold for Pure Titans the way it does for Shifters. With Shifters, the Titan form is generated around an intact human body that stays lodged in the nape—that’s why someone like Levi can cut Zeke out or why a Shifter can eject themselves. Pure Titans work differently: the Eldian’s body fully merges and transforms into the Titan itself. Hange’s experiments (cutting open Pure Titan napes) showed nothing but flesh and no recoverable human inside. The nape is still the weak point because it holds the remnant of the original person’s nervous system/spinal connection, so slicing it kills them permanently—there’s simply no separate “operator” to extract. The only ways a Pure Titan returns to human form are by consuming a Shifter (which triggers a reconstruction of their body via the Paths) or the eventual disappearance of all Titan powers. Until then, the person is fused into the Titan and effectively trapped. That’s why the Survey Corps never treated Pure Titans as extractable captives the way they sometimes handled Shifters.

Tom Ksaver’s Beast Titan took the form of a bipedal bighorn ram with curved horns, a long muzzle, and fur covering its head, neck, and upper body. Unlike Zeke’s ape-like version, it lacked elongated arms suited for precision throwing, any notable hardening, or standout special abilities that would excel against early 20th-century artillery and gunfire. Marley’s military prioritized Titans with clear battlefield roles—such as the Armored for durability or the Colossal for massive destruction—so a form that was only somewhat larger than average Titans and mainly effective at charging or headbutting other Titans was judged low-value for frontline combat. Ksaver himself described the Titan as not particularly useful in war, which aligned with Marley’s assessment and led them to keep him in a research role studying Titan biology and past memories rather than deploying him in battle. He had inherited the power largely for scientific work (and as a form of self-destruction after personal tragedy) rather than as a dedicated Warrior, so the combination of an unoptimized animal form and a non-combatant holder made it unsuitable compared to the more aggressive, specialized use Zeke later achieved with the same Titan.
