Minato who was high level shinobi described Kuramas half as "hevy chakra". You remeber what hapened to Madara when Zetsu infused into him chakra of people under IT, same can happen with TT without body of sage. Moreover, Minato was dead(edo) when actualy using fox power, and dying whe he seald it. Well that`s all can be just my speculation tho.
