Soulhunter Kayn's transformed profile pictures

So I personally don't have the one Kayn skin, but my friend was playing with the skin on his computer and I noticed that after you transform into Rhaast or the Shadow Assassin, the profile picture next to your health/mana is still the default for each transformation. I heard the reason why there aren't many Kayn skins is because every skin they make is pretty much like making 3 (base + 2 forms). If that's the case, shouldn't they make a special profile picture for the 2 transformations? If they aren't planning on making any Kayn skins any time soon, shouldn't they at least make pictures for the only skin for Kayn?

Just a suggestion, let me know if you agree or no.
