Renamed Blendshapes

Problem: A model has incorrect blendshape names. Let's say, "shmouth" instead of "mouth." I want to use native Unity solutions to fix this.

Info: I'm using Timeline to animate models. I don't want to duplicate animation for incorrect blends. I know I can simply take all the curves and make them shmouths. But then that has to be done forever for everything and other people have to know that model (or others) have a shmouth. I want to stay inside Unity and not use any 3rd party apps. C# coding is fine. It's my understanding that I can't put anything on the model, codewise, to intercept the animation curves and remap because they won't ever play because the Timeline recognizes they aren't on the model.

I'm aware it can be fixed outside Unity. I'm aware there are 3rd party products that can smush and rename/reorder skinned mesh renderers. I want to be able to put some code somewhere, anywhere, so the same animations can be used and everyone down the line doesn't have to be aware of 3rd party apps, or models that are different, or animations that are different, or I have to go back out and remodel.

Is there a solution inside Unity?

Sorry for the emphasis, but I think I can save people wasting their time typing solutions I don't want to use or I know of but are last resorts.

Thanks.

 

Since no one chimed in, what I've done as a kind of crummy solution is just add in all the fake names to animation. Since the Timeline won't play a blendshape that doesn't exist, I can take advantage of that.

So if I have 3 models with: Mouth, Shmouth, and wrongpath.Mouth
blendshapes, I can take the curves and simply copy them, changing the property and/or path. So I can have those 3 models on the timeline using the same animation. But the animation has 2 unnecessary curves that it never uses, depending on which model it is assigned to. This is pretty easy to do programmatically. It's not elegant and I have to change any animation I use forever more. But it's a hack to be able to have the same "Yell Like Crazy" animation and it work with every model without making a "Yell Like Crazy Even If You Have A Shmouth" animation.
