It's going to be a little challenging because your PW is really strong at 44 degrees. That's the "standard" loft of a 9 iron. Ideally, you would go 44, 48, 52, 56, 60. But that is a lot of wedges and probably wouldn't leave you enough open spots in the bag for other clubs. I would pick up a used 50 degree, see if you like it and, then, maybe think about purchasing a new set of wedges if needed.
