Wrap-Around Technique in Harp & Celeste Patch

Hi Everyone, I purchased Unify on the recent BF sale and am now digging into patch design. The goal is to build custom orchestral drones, pads, shimmers, evolutions. I also have Corestation to use with BBCSO Core. I am looking at the Harp & Celeste patch in which there is a wrap-around technique within combobox which just maps the limited range of the Celeste across the entire keyboard. A useful and simple technique. However, it would be much more effective if it blended multiple overlapping Celeste instances so that the transitions aren't as obvious--for instance, in the current iteration E3 is a higher tone (probably an E5) than F3, which drops down an octave. If you could mask the transition by crossfading two Celeste instruments that would be better and blend the transition point.

Any suggestions on modifying this patch for a better and subtler wrap-around technique? Would you need to do this within combobox or could you just use a unify layer (I would assume so?) But then, it isn't clear to me why combobox is used in the first place, rather than a unify layer. Suggestions? Solutions? Tips? 

Thanks!
