One of my favorite projects was creating from "Erase The Miles", a bluegrass tune by Third Tyme Out, into a 'in the style of Elvis' backing track for a friend who's an amateur Elvis impersonator.
Very easy to do with BIAB...
That's a great example of what I was referring to. It's unlimited what one can do with a few minutes of experimenting and then some massaging of the tracks and tine. You hit the nail on the head. Wishing you well.
