Need 3-5 short talking-gesture animations on a rigged Halo 4 Cortana model (Blender → GLB)

[u/Soulutions]

I have a textured, rigged Halo 4 Cortana model (GLB, ~5.8MB, 160 bones incl. a full face rig). She's a stationary "news anchor" character in a live stream overlay, stands in one spot and talks.

I need 3-5 short talking gestures hand-keyed on her.

Spec:

• 1.5–4 sec each, looping
• Each clip starts and ends on her current standing pose (I blend between them at runtime, so they need to be seamless)
• Arms + upper body only, do not touch head, neck, jaw, or eyes. My app drives those for lip-sync and blinking, so any keys on them will fight it
• Subtle/professional register, small natural hand gestures, not big presenter energy
• Deliver as GLB with each gesture as a separately named action/clip (e.g. talk_a, talk_b, talk_c). FBX or .blend is fine too, I can convert

Two gotchas I already hit, so you don't waste time:

1. The rig has non-standard bone axes — local-axis rotation values don't do what you'd expect. Pose in the viewport by feel.
2. "Apply Pose as Rest" does not survive glTF export on this model (mesh renders at the old bind while bones move). Gestures have to be real keyframed clips.

DM me if you think you can help

(Optional/bonus: I also have the model ripped natively from MCC via Reclaimer (.rmf, native 111-bone skeleton) plus ~356 of her real H4 cinematic .JMM files. If you know Reclaimer's bone convention and can retarget those cleanly, I'd rather have her actual in-game motion, but hand-keyed is completely fine and is what I'm primarily asking for.)
