Interactive Timeline Control (Attack Combos / Quicktime Events)

Hello,
I want to use Timeline to compose attacks and combos for an Beat em Up game.

I want to use Timeline because of its power. To setup camera positions, slowmotion, particle effects, hurtbox activations and custom tracks, ...

My overall approach is:

• Use a Timeline Asset ("AttackAsset") for each attack animation to define which and when an hurtbox apears, how strong the damage of the attack is and so on...
• Now build combos by using each "AttackAsset" in a ComboAsset (again a Timeline Asset) or other ComboAssets

The big question is.... How to control these AttackAssets in the ComboAsset Timeline

• I imagine to mute single clips or hole tracks
• Is it possible to add Timelineassets through a custom playable to a Timelineasset (I imagine it should be, because it is a playable)?
• Or sould I use ControlPlayableAssets and multiple PlayableDirector on my character (is it then possible to blend between animations?

My solution could be:

• create a custom track to control activations and other playableassets
• create a ActivationBehaviour and a TimelineAssetBehavour for that custom track
• ActivationBehaviour controls whether the following elements in the track should be played or not
  
• TimelineAssetBehavour plays a timeline asset

Is this possible or do I run into a dead end?
A similar approach could be used for quick time events...
