Combining sequencer and blueprint animation

Hit a bit of a sticking point in what I believe should be a simple task. We’re in the process of creating an interactive cinematic which uses the sequencer to control the linear animations, and a gaze mechanic in VR to trigger a number of aesthetic events such as lever pulls and button presses in an internal cockpit. An actor BP contains the single skeletal mesh which contains all the joints required to move the levers as well as lights and SFX. I have a functioning animation blueprint to move the levers on an event, however I am unable to blend/add the animation blueprint to the sequencer animation.

Any ideas?
