Kayn's transformation timer on shorter modes

So hear me out. I like Kayn and I play him a lot but I feel like maybe on maps like Aram, the new Nexus Siege mode, and in general quicker game modes maybe cut down on his transformation timer for the form you didn't unlock right away. For instance I wanted to play as Shadow Assassin my Nexus Blitz game earlier but I had to wait so long for the timer we already won. But before you ask the only ranged champion they had was Twitch so I couldn't really stack towards Shadow over Raast. Just please Riot consider this QOL change to Kayn so he can feel a bit more enjoyable in shorter game modes. Maybe just a minute or two minute wait on these maps instead of the standard.
