in my case i had sent a notarized copy to the university prior to expiration my IELTS and while they asked for IELTS score it was expired hence they accepted my original score copy. I came to know that some university who accept IELTS score can check the genuinity of the score online; but your case is different. Sry to say but I dont think there is any way to send the expired IELTS score to the universities as far as i know.
