Rootless 7alt voicings on guitar

Rootless 7alt (3–♯5–♭7–♭9–♯9). Played as stacked and in each inversion. Practice Lab's voicing search finds 5 shapes, every one movable: drawn here on C (E, G♯, B♭, D♭, D♯), each plays any key moved to it, as the table below shows. A five-note altered dominant recipe; the root is supplied by the bass.
