A split would likely only happen if it were agreed that BTC was no longer viable because of a flaw in the protocol. And more likely as a reverse split.
A currency that didn't have the flaw would have to be developed, mined, and when it got to a certain size and date BTC would be traded for the other currency. Basically doing a migration. Since the new currency would have been around for less time you would trade something like 10BTC for every one of the new coin.
There is no reason for BTC to go the other way. The smallest unit of BTC can be reduced to a smaller size so that the price handles any size transaction. This might be necessary if the whole world moved to BTC, as we'd have a few quadrillion dollars held in a few million BTC so each coin would be worth over a million dollars. But that is unlikely.
