Is there any way to play an animation without a mesh.?

I Have a complex set of pre-computed 3d coordinates stored in an animation file with a simple skeleton attached.
i want to play the animation and read off the bone world coordinates. without having an attached mesh.
this is useful in our situation as generating the complex data at run-time would be processor intensive.
reading the bone info is not a problem. but animating a mesh that is not required is a waste. also if we look away from the animation it is culled and the animation and therefor the data stream ends. it comes back if we look back at the animation.

we also blend between these data streams using the Anim BP so simply using an array of elements wont work.

any help in this matter would be great.
