You're missing lots of options that have been proposed:
microbitcoin
microbits
micros
mics
µBTC
uBits
crobits
zib
It's not much use as a poll if you've already limited it to your two favorites, including one (renaming "bitcoin") that's nearly impossible to pull off without major confusion and risk of money-losing errors.
I did not pick my favorites.
Then why did you include your snowball's-chance-in-hell favorite choice, 'bitcoin redefined as 100 satoshi', but none of the others?
