No. You must not reassign an inactive affiliate to the active affiliate. Although there is a chance that he/she might get active but the chances are very little. Also the active affiliates under you might feel little conservative by your decision. They might feel that they are being rewarded an inactive affiliate for their honest and active working.
So, better not to do it and keep the affiliate with you and try you could make them active and then transfer to the active affiliates.
