You can drive morph target values from blueprints, maybe from animation blueprint also.
With different meshes problem is that you need to recalculate one morph target values to another mesh morph target. And for this i do not know about any automatic way, I only know that skyrim has tool for it, and modders there do it all manually with that tool.
for skyrim there is tool, google for: “skyrim bodyslide studio convert” warning most results not quite work safe
