Replacing a Shape While Keeping Keyframes in After Effects

Hey everyone,

I'm working on some simple Lottie animations and have already created an animated design using circles with different stroke sizes around them. I animated them with keyframes and now want to recreate the same animation but with different shapes—hearts, diamonds, spades, and clubs—instead of circles.

I know that in After Effects, you can replace footage and images, but I haven't found a way to swap out shapes while keeping all existing keyframes intact. Does anyone know a way to do this?

If there's a plugin that could make this process easier, I'd love to hear recommendations.

Thanks in advance!
