Hi Paul,
welcome to the list.

Hand cranks should be possible. I have already thought of a leg/arm driven
python. A separate rear arm drive opens a lot of nice possibilities, but
will
make the python 5 kg heavier.
The easiest solution I can offer is a leg/arm drive by simpy pushing your
knees with the hands. This brings some extra speed, but only temporarely.
Also the knees are stressed more than usual.

Make it, ride it, and then we will see.

20" - Yes.

This is not possible and will not be rideable.

Nothing more than you can find on my homepage and in the list archive.
