I purchase a bunch of items in the duty free shops, including, say, a suitcase into which I put them.
A number of airports are able to take your bags in this scenario. (Many airports are little more than shopping malls with runways attached, so it is in their interests to allow this.)
For instance, Heathrow Terminal 5 has a specific bag drop desk at the airside customer service desk in the middle of T5A.
The airport has a luggage holding service past its security check and passport control area (I'm not sure there are such airports at all in the world), and I have deposited a piece of luggage there at an earlier time.
Qatar's business lounge in Doha has a dedicated and manned luggage storage facility, turn right as you enter the lounge, it is beneath the restaurant. Many other airport lounges will hold bags if you ask discretely.
A friend of mine on the other side of the security, passport and customs checks walks up to the airline's counter, with a duly signed and notarized letter from me asking that they carry a second piece of luggage.
If you are unable to check it in yourself in person, the bag should be shipped as cargo.

In scenario 1 - just gate check it. You won't be the first person to have bought too much at duty free. Gate checking is sometimes done without regard to previously checked bags or fees. But keep in mind, gate checked bags are hand tagged and not always in the tracking system, so sometimes harder to find if they go astray.
In scenario 2 - you should be arrested for stupidity.
In scenario 3 - again gate check it.
In scenario 4 - the check in counter agent should be arrested for stupidity if they allow it. Papers can be forged, you should check your own bags.

There's another scenario, which happened to me. I was flying ORY-AMS-GMP (yeah a long time ago) on KLM, and checked in one large piece of luggage, keeping the rest with me, which was well over any reasonable limit for carry-on items. Luckily enough, ORY was always a backwater airport, and it was pre-911, so security was lax. I got on the small plane for ORY-AMS, and had about 40 kg of luggage with me in the cabin.
The flight attendants did look at me in a puzzled way, but the plane was empty -- something like a dozen people -- so it didn't matter much to them.
When I transferred to the AMS-GMP flight, on a 747 packed with rowdy Korean tourists overloaded with duty-free purchases, one of the KLM gate employees saw me, and in a very stern voice called me over. No Sir, I cannot not let you board with this much luggage. I point to the Korean pack mules around me. He shakes his head. No Sir, you are way beyond that... I don't know why Paris let you board with this much luggage, BUT I will have to send this one to the luggage hold. Free of charge, since it was KLM's mistake to let this come aboard the first plane. pointing at the larger piece of luggage. He filled out some papers, and gave me a receipt.
And indeed my two pieces of luggage were waiting for me in GMP. So it is indeed possible, but whether it will be free, and whether they'll make it in time is another story.
