Really Cool.

For the higher operators, you can use the letters from my Letter Notation:

You won't even have to change the symbol for repeated exponentiation (though it will be interperted as an english E rather than a greek epsilon).

So we'll have F instead of "4", G instead of "5" and H instead of "6"
