Why on earth would you reuse such a long-established name? Pico has been around for 35 years and many distros include it by default (or symlink `pico` to nano, anyway).
Post GPL3 Apple replaced GNU Nano (itself a Pico clone) with UW Pico. A step backwards perhaps, but nano is a symlink to pico. I'd steer clear of anything that looks/sounds like 'pico' including 'piko' which doesn't seem to clear anything up.
