Brother feels left out of wedding....PLEASE READ!?

My brother in law is more like a brother to me than my 2 actual brothers. He has been in my life since I was 8 and I would love for him to be in my wedding but I cannot think of a way to involve him. My husband to be already has his 2 groomsmen picked out so that isn't an option. Any suggestions would be greatly appriciated! :-)
