I am from Hawaii but live in Michigan. My sister just called asking for me to adopt her unborn child

This is a tough question for a Michigan attorney to answer. The laws of the state where the baby resides would be the ones governing the possession of your niece/nephew, and it is doubtful any Michigan lawyer who reads your question would also be licensed to practice law in Hawaii and therefore competent to give you a professional answer.
If your sister was a Michigan resident, the law would require not only her, but the father, to sign away parental rights before you could legally adopt the child. With the identity of the father supposedly unknown, that might cause a snag to any legal adoption.
You need to seek the advice of an attorney in Hawaii, as laws can vary significantly from one state to another. Once you have been named as the person entitled to legal possession of the child by an Hawaiian court, whether via formal adoption, or some sort of temporary or permanent guardianship, it should be much less of a problem to bring the child to Michigan to live with you.
But, first things first. Try and speak to an attorney in Hawaii about this.
