Hey, if the ramp and cargo door mods are indeed swappable then fine, that limitation is gone. If it’s tanker-only and no cargo beyond pax and hand-loaded stuff/bundle loads, then not a problem. That’s what Boeing did way back in the day to make the C-97 the KC-97. But those cargo doors were basically bomb-bay doors but at the back , modern airlifters the ramp is part of the cargo storage area, a lifting aid, part of the structural integrity for stuff like ditching, pressurization, etc With the boom on there tho, how ya gonna load the palletized fuel cells? That looks awkward. Or put them in before the boom ramp/doors?
