Sorry to disappoint you, but Minato didn't make sage rasengan in kurama mode. Minato just created the Rasengan itself, then he offered Naruto (who already entered SM/KM) to add senjutsu chakra in it, and he did that. So Naruto was the source of senjutsu chakra in this Rasengan, not Minato, since the latter wasn't using SM back then. And since Minato didn't decide to combine SM and KM the same way Naruto did, despite having some mastery over both of them, it means it just wasn't possible for him.
