Having done a bit of exploration of the intent of the limited C&R "license", I can state with conviction that it does allow "direct" purchasing and shipment with intent to build a collection and presumably some "trading" (resale) but is quite explicit that "dealing" even solely in guns classified C&R is not permitted. No quantitative threshold for volume or frequency of sales which would constitute "dealing" is stated. Flying below the BATF radar (no FFL) may work for awhile but when found out, I don't think the "stealth" license or the appearance of injured innocence will be much of a shield against prosecution. Every man the arbitrer of his own abilities in skating over thin ice.
