No, definately the Lancaster ! - They didn't have but one B-29 in the U.K. anyway, and the conversion needed was extensive....There was no need to use the Bomb on Germany ! - We had them on the run, and besides, Patton wanted all the glory. - As far as the Lancaster went, they just needed to put on some Griffons and pressurise the cockpit, no problem !! - Another reason they chose to drop them on Japan INSTEAD, was Japan had it's own little nuclear program and Allied Intelligence couldn't find-out exactly how far they were with it, they couldn't infiltrate 'honkey' agents in to find-out, so they got the Big Delivery...everything indicated it was going to be a real bitch of a scrap to beat them, their terror Kamikaze's left no doubt that if they had a Bomb ready, they'd use it too - We bet them to it, and as it it turned-out, they weren't all that far with their nuke program....tough-titty, they were the Aggressors and they got scragged...I don't know why you insist that they were going to A-bomb Germany, it was already getting pretty 'munted' by the RAF 8th AF, Hitler had obviously over-committed themselves to 'history repeating Napoleon', they weren't hysterical, fanatical barbarians like the Japs...dedicated Nazis perhaps, but captured Germans were not all party zealots, that's how we got so many aviation radar advantages, quite a few Luftwaffe types saw through the High Command's bullshit, and defected with their planes, plus, as I've said before, we neutralised their nuclear program...something we COULDN'T do with Japan....
