A Ribbon Mic placed about 6 to 8" away from the hole... or the best mic you can get or barrow. record dry add all fx in mix. really I not qualified to answer this but that's what I would try... Oh maybe place another Mic away from the guitar and a condenser Mic at the hole with the main one... I bet you could get a huge sound with this setup...
