This is a candidate for precast. I don't know your area and what is available but a tear out and footing install for a set of precast to veneer could be a direction to go in. A new set of precast stairs is a blank slate for most any kind of look you want. you can go to realstonesystems.com and stonecraft.com to get a idea of what is available. I don't know your demo cost is but hear I can get a precast placed for me for less than a G. give or take depending on the rise as long as I have the area prepped.
