Used game add-on code on wrong inactive GT

Hello everyone,

I’m having some trouble and was wondering if people could help. I recently added the code of my maps, forward unto dawn, and avatars for Halo 4 Limited Edition to an inactive account accidentally. My primary account is in the same Xbox, I was wondering if I download the maps using my inactive Gamertag, will I be able to use the maps on my primary account? I understand that my code is gone but I was just wondering if there was a remedy for this. Thanks everyone for your time and help.
