Think we might see landings in Greece along with Dragoon? Churchill says "told you so" and maybe gets his way, even as an all-British affair?

About the same as OTL. If the D-Day invasion fails, that will free up hundreds of thousands of German troops for the Eastern Front.
Up to a point.
The Germans for a long time believed that Normandy was a diversionary attack, and were waiting for the main attack at the Pas de Calais. It would probably take a couple of months before they would release large numbers of troops to the East.
...
However - If D-Day fails, then the hundreds of thousands of reserve troops the Germans sent to France in OTL June-August 1944 won't be going there.
Dragoon was two-purposed - logistics (as you say) but also to move some US troops out of Italy and into France.Wasn't Dragoon a secondary operation intended to open up the ports of Southern France to assist with the supply situation in Normandy? If Overlord fails what's the impetus for Dragoon? Just to show the Russians that there's a new front in France?
Geographically the Germans still have the advantage of digging into the mountainous terrain of Northern Italy and the Vosages so if Overlord fails the Allies will probably have to try again in the spring of 1945. How much that delays the Soviets with the shifting of forces East is a good question.
The OP wrote "the Allies lost at D-Day" which implies an immediate repulse.The OP does not precisely define how the invasion is defeated, including how long it takes and how damaged the defenders are.
