Re-using Moen Valve Body | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

I am repiping my house to PEX from polyb. I have a bathtub (tub only) with a valve body that has polyb connections soldered in (see pic). I don't want to get a new valve body, but removing the connections is impossible because of the solder. Any options on reusing this valve body without buying a new one?
