Is there a way to modify sprite's vertices

Questions & Answers

There are many prefabs in my project. Each contains a SpriteRenderer component. They all use a sprite named “spriteA”. Now I want to replace “spriteA” with “spriteB” . The problem is that “spriteA” and “spriteB” has different sizes(256256 128128). Which means I have to modify every prefab(set localscale to half). I don’t think it is a good solution. Is there any better way?
I know i can do something in AssetPostprocessor.OnPostprocessSprites.But it seems unable to scale sprite’s vertices.

Change PPU to match the scale.
