Neither "久しぶりにしたことがある" nor "久しぶりにしたことがない" is a correct sentence. If you hadn't done X in a while and did it now, you can say "ひさしぶりに X した" ( did X after a long blank period ). If you haven't done X in a while and still continue not to do it, you should say "ながいあいだ X していない" "久しぶりにした" is an action at that specific moment after long time. And "ことがある" "ことがない" means "(don't) have experiences". These phrases can not be connected together because the meaning is not relevant.
