I don't have the time to dig into that, but I think Cassie's suggestion from the thread linked below might be suitable for something like you intend to do. In the demo below I added a tween to the timeline of that example to sort of show the concept you could approach. You might also want to get a closer look on how durations and the position parameter work with tweens on scrubbing ScrollTriggers.     See the Pen ExoxaMo by akapowl (@akapowl) on CodePen
