Bitcoin + Litecoin + Peercoin = used together?

[Blazin604]

Hey guys...just wanted to get your thoughts on this. Do you think Bitcoins and litecoins and peercoins could be used together almost as the same currency but with different values? For example, I was thinking Bitcoins would be used for large purchases in the future i.e. a house, car, real estate ect. and litecoins would be for day to day expenses such as gas, groceries. Peercoins would be similar to pennies....anyone think a system similar to this could work? It would still be a one world currency we would all be using "crypto-currency"

Peercoins are not made for micropayments. They do better as value storage (because of the PoS "interest rate" and the realtively high transaction fees) and for large buys.

Micropayment-friendly currencies are Litecoin and, for example, Primecoin.
