Hmm, I imagine you wouldn’t need to. For your example, just using the tuoproximal demonstrative (i.e., that near-you book) would imply that the book is far away from the speaker — otherwise, they would’ve used the omniproximal. I could see two being used for emphasis though.
Interesting. Could you combine them? As in, could you use this system to really simply say like “this far-me near-you book”?
