All the trigonometry symbols look too much alike. (Small round things with small scribbles of size of the ant's leg attached to them).
Likewise, base-8 numerals look fun. However, one benefit of the regular numbers is that they look both pleasant and distinctive from each other in the flow of the regular text. Both in print and also if written by hand (at least if you add the extra horizontal bar to the 7).
Actually, if one were to adopt all of the proposed notation, it appears that one might lost in the forest of slightly different combinations of arrows that mean different things.
The quantifier notation is the only thing I actually might like. (It's also backwards-compatible.)
