Nope. Jman never mastsered sage mode. His was incomplete so minato would only get as far as he did. The evidence is mounting bro, even hashirama has sage mode LOL. Uzumaki are blood relatives to the senju, so descendants of those lineages are potential candidates to master it. You'rejust being a hard headed minato fanboy......just asking you to think and use the manga.
The reason why Jman & Oro never mastered it, is that they didn't have the "perfect body". When naruto was training, the toads told him that your must must be strong. High vitality and a big enough chakra pool to contain both your normal chakra and natural energy. There is a reason that only hashirama and naruto obtained mastery. Kabuto was able to do it because of experiments, which he used karin's dna. Karin = uzumaki descendant. Just like hashirama's dna, it gives people a "better body".
