If your ATH-TXL is the one at 0840 then just nap in the A3 lounge. You will likely be the only person there from 0400-0530. If it's the 1330 flight then possibly worth a hotel though I would just have some coffee and take the metro to the city and back.
So, did A3's computer consider this a transit of LHR and not charge you the extra taxes for upgrading? It should be fine at 2100 but I wouldn't try a back-to-back on the other 2 flights.
I wonder what the flight attendants will think when they see you getting back on the flight. 9 hours is a long time to be going nowhere
