I agree with everything SuStel said there, with the addition that the point down triangle can be used with conjunctions particularly in a list of complex noun phrases and for multiple conjoined sentences.
What I outlined as my aesthetic preference doesn't include
conjoined complicated noun phrases. I think I'd need a third
symbol for that, if it were absolutely necessary. If we can figure
out compound sentences like 'uSDaj chop chev, I think we
can figure out complicated noun conjunctions.
