There isn't necessarily anything wrong with mixing and matching these two features — taking the ability score bonus of Feral and swapping out the Infernal Legacy spells for the Zariel spells — but you are cherry picking features from two different treatments of the Tiefling — one published officially, and the other published in rough draft form. It could have unintended consequences, and some groups prefer to minimize those.
And, as was said upthread, once you opened up UA, you left "legal" behind. With UA, you are already in the realm of home-brew, and should work collaboratively with your group to make sure it works.
My general feeling is, whenever you mix one Extra feature to combine with another Extra feature, you need to be careful, and you should check with the DM to make sure things will work the way you think they'll work. Ultimately, it's the DM's job to manage the balance of the game and the group, so it's best to be as communicative with the DM as possible to make sure there won't be any problems.
