Wonder if A2 operation with USB tone modulated code would be legal on
these bands?

Probably not. Unless of course, you retitled it "pentature encoded tone
shift digital modulation". Morse code is really 5 different bits of
information, dit, dah, between character space, between letter space,
and a between word/empty space. If you count the space between messages
as a seperate data point, then it becomes hexature encoded.

Bear in mind Morse code was designed to be used in a mechanical punched
tape sending device. It was never meant to be sent or received by hand.
It was just by accident that an operator found out he could copy the message
directly into his head by listening to the sound of the pen.

Vail, not Morse, replaced the tape sender with a hand key, and dropped
the pen from the receiver.

Like "diHydrogen monOxide", it could become popular on the Internet.
