Considering AF's love for cost-cutting, I suspect that this is extremely unlikely either. A few such shuttles have been organised by airlines (e.g. QF-AA at LAX, BA-AA at ORD, etc) but airports charge them an absolute fortune for the privilege. My sense is that AF-DL are unlikely to want to go that way.
