Rokien's new thread on multiple character slots

although U/U items might be a problem.

I don't see any issues arising sharing U/U items between your own characters (Although you may be right in the case of quested gear they may need to add a extra tag to items to bind them to a character)

or perhaps certain items preform a check on your quest list not allowing you to hold them until you are finished said quest.
