Don't think so. An FFL receiver renders unto Caesar; a "third-party FFL" acting in a consultancy capacity has nothing to do with law. Example: You want to buy a gun from a PI in Minneapollis. PI takes guns to local FFL and this worthy vetts condition and reports to you the prospective buyer. Precisely what BATF rule governing the shipping of firearms is satisfied by that arrangement? You can't use this FFL as your FFL receiver unless you live in Minnesota and it's not even likely you'd do so as a Minnesota resident depending upon your ditance from Minneapolis. I agree with jOE.
