Multiple types in a params without casting?

Feel like I'm hoping for an unrealistic expectation, but is it possible to have multiple types in a params without casting to avoid GC? eg...

        public void DoSomething(params object[] objs)
        {
            for (int i = 0; i < objs.Length; i++)
            {
                if (i % 2 == 0)
                    Debug.Log((int)objs[i]);
                else
                    Debug.Log((string)objs[i]);
            }
        }

        public void DoSomething(params object[] objs)
        {
            for (int i = 0; i < objs.Length; i++)
            {
                if (i % 2 == 0)
                    Debug.Log((int)objs[i]);
                else
                    Debug.Log((string)objs[i]);
            }
        }

you can use generics:

    private T MyMethod<T>(params T[] vals)
    {
       // ...     
    }

    private T MyMethod<T>(params T[] vals)
    {
       // ...     
    }

That wouldn't allow for multiple types Unless you use object, you can't have an array of multiple types You could make a kind of wrapper type which represents one type or another, but there is no built-in way to do this.

okay thanks. I'll probably just eat the cast cost. its not really super performant crucial and shouldn't hurt anything in the long run.
