It certainly doesn't feel like a far more balanced manner with Ymir fists personally! But other than that, I also think that it could be cool if the whulf set just made your kadouha better? Sort of like how Eresh's potential unlock can make Eclair Lacroix way stronger, perhaps the Whulf set can change Kadouha in the following ways:
1: Kadouha obtains a 3 turn Cooldown.
2: Kadouha's damage is increased by 50%
3: Kadouha's explosion is twice as large
(Maybe it also grants the Kadouha skill? Its probably strange for a weapon set to only be usable in one specific class.)

Shooting star has always been useless due to not having the normal weapon scaling in it.
