Playing Santa

I know that Gabi has Ari, why are they using an ethnic actress to play the role, yes, granted Ari is Gabi’s daughter, but remember, at the time that the Udell girls were playing Ari, Freddie’s Sonny had brought up seeing everything Will in Ari, & now they are depicting Ari as Cher slash Gabi? Why not have Zach’s Sonny playing Santa to Ari?
