You can crumb coat with cream cheese and then add the final coat, but remember it's a perishable frosting, so you'll need to keep it refrigerated. If you're worried about the consistency, you can add more powdered sugar. There is a crusting cream cheese recipe out there if you search for it apparently, but I've never used it. A crumb coat doesn't necessarily have to be crusting, as long as you just leave it to set up for a while before applying your final coat. If it's cream cheese with butter added, it will set up nice and firm in the fridge and allow you to apply your final frosting layer without disturbing your crumb coat.
