Orc-Men and Man-Orcs definately weren't Uruk-Hai. I imagine the former as something between men and orcs in looks,the latter as super-Orcs with all Orc features more strongly developed.
By the way,Ainur were definately able to multiply.The Valar didn't seem inclined to do this,while several Maia might have hybridised with lesser creatures.
