My first thought was "When did he go Boskonian?" as I imagined someone biomoding a baby and a tree to do this.
After calming down and thinking about it, I got over my immediate knee-jerk reaction and considered this. Fen-realistically, you'd need a second-gen Tree to even start. And Ki won't be doing that for decades, not sure about the Yggdrasil-class.
Then you'd need to cross-biomod both the tree and a person to make the link, and make sure the biomod was inheritable and both bond-partners were (to borrow a phrase) fruitful.
Quite frankly, if a person wants to live that long there are other, much easier ways to go about it.
