At least one person [1] has played with using APL symbols in J, at least at the display level. I gave it a try, but was surprised to find that I preferred the ASCII version. Perhaps if J had its own custom symbol set (extended from APL?) it might have been better -- not all of the APL symbols have exactly the same meaning in J, and I remember finding some of the differences to be a bit jarring. For example, conjunctions like '&>' and '&.>' are heavily used and deserve their own symbols -- just putting a little-circle before a '>' feels like a hack. (No disrespect intended to the author, though, this was a great experiment.)
