I've been playing around with this idea for some reason, mostly because I am a big fan of Derek Parfit.
Since appearance is memory, form, the past, in an OOO reality one should be able theoretically to “photocopy” this appearance and “paste” it onto another entity. This would be the equivalent to Parfit's teleportation machine and certainly equivalent to quantum teleportation, which has been done already.
In a world of weird essences personal identity is real yet a paradox—it is not metaphysically present, that is to say, it is not welded onto an essence that is fundamentally different from it.
Thus one can have a “no-self” view that is not reductionist.
