Well, I have never been very clear on the relation between tp and Daoism. Despite books like Mysticism and Logic, and Alice, a mystical viewpoint seems to provide little guidance for a language, since one of its major points is just that words inevitably falsify preceptions. Simplicity here is just not making distinctions and thus not forcing things. Grammar is all about distinctions and rules and without them, communication beyond a certain level becomes impossible, But tp is certainly well beyond that level, so it needs rules, fine distinctions, categorizations -- all the things that Daoism isn't.
All that aside, if your system can generate all or most of the accepted sentences of tp with the same meanings, even if different syntax, then it is worth looking at within the tp context. If it can't (and your examples tend to point in this direction), then not. On the first alternative, it would be especially telling if you could provide better explanations for cases that are accepted but uncomfortable,
