I remember some such spheel about Naruto's 4 trigrams seal being double-layered or something, and then one more layer was added by Orochimaru(although shoddily done), which made it impossible for Naruto to draw on the Kyuubi's chakra.

The Hachibi is sealed in with the Iron Ox seal, but I really see no reason as to why Minato can't just add a 4tri seal over it as another layer, or use the same sealing jutsu Orochimaru used, both options which would theoretically separate Bee's Chakra from the Hachibi's.

Therefore, I honestly think Minato can easily win this with his mastery of sealing jutsu. Aside from perhaps the god-tiers, I can't think of a better fuinjutsu user than him.
