It'd be entirely possible to pay any number of consultants a shirt-load of money to do a cost-benefit study, typically on the basis of derived financial metrics. Of course, they'll still include a section on what they can't turn into money, and you'll be back at exercising some judgement. Mind you, this particular investigation would be far more tractable analytically than many they turn their hands to.
Would it be a good idea? Probably. Who pays? Don't know. Maybe find a community-spirited consultancy. As an aside, a few comparable studies of volunteer organizations have returned verdicts of substantial previously-unquantified benefits - might even be the case with AF. Of course, many people in those organizations didn't need boy-scout consultants to tell them that they were doing good things.
