Hm.  On reading this, the first use I thought of for conjunctional "slash" was for creating synergistic meldy concepts, "boat slash hovercraft" or whatnot, much like "cum" in classicising style.  If that is to have a Boolean reading at all "and" is the more appropriate one; you can't be a boat-slash-hovercraft by just being one of the two.  I can see there some examples where "or" is an adequate gloss -- Wiktionary offers "I think I'm having hallucinations slash someone is playing tricks on me" -- and I think that what you're judging to be inclusivity I would rather judge to be a stronger semantic bleed-through from examples like the first: a situation can't be described as having hallucinations *slash* being played tricks on if it's clearly just one or the other; it needs at least to be the kind of situation which has the common features of both, such that I can't tell.

Your long-term imagining seems possible to me if indeed the clusivity contrast is one that can be stable in a natural language, and that I'm still out on.

Come to think of it, does any natlang have different words for "one (or more)" and "only one", or the analogue for other numbers?
