Undoubtly this is an interesting concept. However having your phylactery on you is probably unwise. The lake thing could have its benefits, as could the tree hiding place. It's best not to bring up your plans though, you never know who will be watching. Liches may be powerful but they do have their flaws. Also it kinda reminds me of lord moldy-butt (voldemort) and brings up the question. Into how many parts can we break our soul? Or only one phylactery is possible?
It has been mentioned that the soul can not be broken up, however, there are other methods which might accomplish a similar result. An unexplored called out part of the Easter egg in the first DJ [hidden under "Once Borns and more powerful souls"] hints at soul binding to the various Spirits of objects and nature [which are further mentioned in some QnA]. While pointed out in https://chroniclesofelyria.com/forum/topic/91/the-great-dev-journal-easter-egg-hunt the mechanic of the Easter egg was not recognized. Then when soul binding was later mentioned for use in marriage Caspian said they had already been working on the mechanism for something else and it was still not recognized. A relic essentially has its own Spirit closely tied into the Story and therefore has unique general Story based requirements for its use. So what about Spirits to non-indestructible objects which may have formed connections with certain Children of Mann. While the Ring of Sauron [which was destructible] acted like a phylactery it did not in fact hold his soul, it had its own Spirit which had the single goal of reuniting with its bonded master.
That also brings up what may happen if the Spirit of a House, Cart, or even the Land itself was awoken and bound to someone. Imagine that person losing control of it thru adverse possession or coup. The new owners may have to contend with the Elyrian equivalent of a poltergeist, killer cart, or a moving castle.
