Don't change your whole set for stud antes. In a 2/4 chip set the bring-in could be 1 chip with a button ante of your choosing, perhaps 2 chips?
Also moving to 4/8 would basically require double the chips!!

Button ante is so much better in a home game, otherwise one would spend half the time asking each player if they ante-ed.
For Stud, as you said, 1 chip bring-in, 2 chip Sbet, 4 chip Bbet with a 2, 3 or 4 chip Button ante.
