Donating breast milk

I have a very bizarre question and I thought maybe I'd ask the ladies in here if you guys think this is a good idea. I am currently a momma of 3 and recently had back to back miscarriages (both pregnancies were a surprise following infertility with my other children) my husband and I are really aren't sure if we should try again and have another baby or not but that's a whole separate battle. It's been on my mind a lot lately about ways I could honor my angel babies and I my brain has come up with this idea about relactating for a few months for the sole purpose of donating breast milk. I think it would be an awesome way of helping moms and babies in need but I'm not sure if I'm crazy for the idea? What are some of your guys opinions? All opinions are welcome!
