This is basically what I was thinking too, and there are some details to be worked out....

Concerning Teach having two abilities, there really isn't an explanation for that yet aside from him being abnormal. Maybe he had no soul to begin with, or maybe it has something to do with the Yami Yami no Mi (a devil fruit that consumes other devil fruits maybe?).

I don't really see the problem with Brook's fruit. This was the ability of that particular fruit, where (in my guess) the soul of the Devil Fruit latched on to Brook's soul and guided it back to the body. When Brook dies again, the fruit will then act as normal. No, the fruit hasn't respawned yet because the owner is still alive (the fruit's lifeforce still has a host).

The whole inanimate object thing is tricky. Swords and guns are not really suitable replacements for devil fruits, so my guess is that vegapunk has somehow found a way to capture or guide the lifeforce of devil fruits into inanimate objects (I feel a connection to Ghostbusters.....).

And just to make sure, are we all saying that the lifeforce of a devil fruit cannot just go to any random fruit, it has to go to the "base" fruit (apple for the Sara Sara no Mi, banana for Kaku)?
