I was only earlier as I said looking at its intended role and then looking at something that saw service as a recon platform that was originally intended to perform a similar role. I know the B-36 Peacemaker had better range with better engines than a German Amerika Bomber could have with the engines available. Looking at the original concept with the original planned engines, could the B-36 Peacemaker have made the mission, and if so, the question comes up of whether the Amerika Bomber could have done it. We know the B-36 Peacemakers made the way into Russia as photo aircraft penetrating deep into Russian territory... Would be it possible to do a rough calculation of mass versus drag and distance to work out how much fuel would be required to do a mission that long?
