Blending animation tracks?

[entangledothers]

Would it be possible to find a way to blend between two animation tracks (in a gltf) with cables? Having multiple tracks and triggering them is fine, but that can lead to some rather jarring transitions as if the timing between tracks isn't just right there can be sudden jumps and jarring skips.

edit: something akin to this type of blending functionality: https://threejs.org/examples/#webgl_animation_skinning_blending
