Can you Replace an iPhone4s A4 Chip with an iPod 5th Gen A5 Chip?

I have an iPod 5th gen and an iPhone4s and i heard the chip inside the ipod is faster and i barely use my ipod so is it possible to replace the iphones chip with a faster one?

No. The circuit boards and other components and firmware are designed specifically for the type of chip already in the device, so just because they're similar doesn't mean they are interchangeable. The chips are also soldered, not in a socket (this saves space, cost, and weight, and improves reliability).
