thought of characters where the transformation would be (visually that is) completely redundant:

Kisama tha shark sage, no one would ever notice the difference, he could've been in it from his intrtoduction and no one would know it! he certainly have enough chakra to qualify

Kidomaru the spider sage: he got six arms and an extra eye already

and now to skip the jokes

Chimaera Sage Nagato (the sheer number of summons of his makes it hard to give him a specific one)
