Suggestions on effects animation

Say I wanted to do a frame animation for a pixel art object. where it Glows and the glow effect expands around the core of the object. (Like a light turning on). I have collisions set on this object, so obviously I don't want the hitbox to expand based on the glow frames I'm adding. How would you guys suggest I manage this in pixi? I thought about adding an entirely separate container just to handle effects animations. But that sounds like it might be a headache to manage with my code, and like it might be taxing on the system.

Thanks!
