Ok, yes, it can work. You can cut out the feeds. Do you want the bad news? She might still wake up. But you can try and see if you get more sleep. (I have my fingers crossed for you.)
She will be upset and cry, but you can still be a caring, loving and responsive mother to her even if you don't feed her every time she asks.
Does your partner help at night? That often works well, too.
Good luck!
