if could change the actors characters, who and what would they be?

i like the normal cast but if i change it. it would be
elena- selena gomez
damon- taylor lautner
stefan- justin bieber
caroline- demi lavato
tyler- wilmer valderrama(. no misunderstanding couse i put joe jonas as klaus becouse i want klaus and caroline to be together. and for tyler i put her real boyfriend.)
klaus- joe jonas
bonnie- miley cyrus or toyler swift( becouse t they are close friends to selena gomez.)
jeremy-liam hemsworth
matt- nick jonas or david henrie
i like selena and justin that why my cast is based on selena and her friends)
