Well, reincarnated (Edo) hosts in the series were left unconscious from the extraction of tailed beasts according to the wiki. The only way to survive was to have a constant stream of life force coursing through the veins after extraction, meaning that the tailed beasts likely were somehow connected to the life force of the jinchs in some way.
Think about it. The Ten-tails husk had its chakra sapped from it: that chakra was then used to create the tailed beasts then. Logically then, that chakra being placed in a lesser vessel would have a certain relationship with the subject's physical energy. Without sufficient life force (I don't want to confuddle physical energy and life force too much, but they do interchange often) one cannot even be a jinchurikii (the 10-tails requires a living host, not a reincarnated host, for example).
Having the tailed beast extracted then likely also drains the life force of the jinch, eventually leading to death unless a constant life force is kept through them, or that lost life force is somehow restored. Just theorizing stuff up here.
The point of the matter that's relevent to the topic though, is if gifting a tailed beast for someone without naturally great life force is more dangerous than simply losing it in a biju battle (OOC), then what would be the point of gifting it in the first place? Heck, IC-wise, no one who values their life would gift a biju to another individual very willy nilly simply because of the risks involved.
It kind of conflicts with the point of doing an OOC match in the first place, where you win or you lose, you lose or win a tailed beast, and you move on with your RP.
