With the way your team looks, I would say just give up on saves because you must already be way behind or try to grab some of the guys off waivers. Rather than giving away one of your top players for two closers I would say just hit the waivers and try and grab some of the new closers: Alfredo Simon, Jose Contreras, pay attention to who is going to get the saves for the Brewers, etc.
If none of those guys are available, then maybe try to work out another trade packaging two guys or two separate trades. Personally, I just wouldn't want to ship away Crawford. Your offense is definitely stacked though.
