In general you can convert Sprite to Mesh with this:

 Mesh SpriteToMesh(Sprite sprite)
 {
         Mesh mesh = new Mesh();
         mesh.vertices = Array.ConvertAll(sprite.vertices, i => (Vector3)i);
         mesh.uv = sprite.uv;
         mesh.triangles = Array.ConvertAll(sprite.triangles, i => (int)i);
 
         return mesh;
 }

That actually looks like it would work. Though wouldn't you also need to add the $$anonymous$$eshFilter and $$anonymous$$eshRenderer?

I think you can assign that generated mesh directly to $$anonymous$$eshCollider, but I didn't try that yet.
