So I just realized you meant can you remove a conference entirely. No, but I like to tinker.
I'll just modify the Big East, probably move C-USA there, split the MAC into 2 groups (MAC East will be CUSA, MAC West will just be the MAC).
The +1 will be the hard part, because to do it I have to play the whole season, then go back in time to a saved pre-season dynasty, schedule the #1 vs #4, #2 vs #3, and then go back again and do it yet again.
Thank you all for following. I had a lot of fun and will continue to play this dynasty, but posting is now finished. I will post all the bowl results either tonight or tomorrow.
