Just so you know, Reallusions CrazyTalk and several other animation apps do work with latest macOS, and are not 32bit programs.
I have used CrazyTalk in the past as well as Blender. Blender has a very steep learning curve and Mac support isn't always the best. CrazyTalk and Cartoon Animator have easy interface, but not nearly as powerful as Blender.
My biggest issue with ReaIllusion is their pricing schemes and add-ons. Look for discounts up to 1/2 Off MSRP. CT/CA worth a try. Think you can do this animation with the programs and it is reasonably easy to create the rigging necessary. Haven't used these programs in a few years, so not up on latest versions.
They have a free 30 day trial with watermarks if you want to try it out.
