What if the decimal place was moved in bitcoin to give a 1:1000 split? If collectively everyone used the term bitcoin for the unit of value we currently call a millibit or mBTC making the total eventual supply 21 billion instead of 21 million, the price currently would be ~$16.70.
It seems to me that the problem of switching to a smaller unit at the moment is that the fees would be more expensive than the same unit of account.

And more importantly it would be a mess coordinating the change in all the exchanges and... now that Bitcoin it is so mainstream how to explain the MSM that Bitcoin has gone from $17000 to $17?
A mess.... even an almost unknown coin such as Byteball, which would greatly benefit of that change, would have difficulties doing it. Bitcoin? Forget it.
We can keep doing forks as some sort of stock split though
