"Imagine an ... iPhone with a very powerful processor..."
One major problem with the iPhone is its short battery life.
For a device that is supposed to be carried with you throughout
the day, the current iPhone has marginal battery life. Add
a faster processor, and that battery life goes down even faster.
I'm not saying a faster iPhone is a bad idea, only that there will
have to be a compromises in size and/or weight to give the new
device enough battery life.
One of the advantages of a larger device (iPod Touch XL? iPad?)
is that there's room for a larger battery!
"to work on both the AT&T and Verizon Wireless networks."
Today, Verizon's network uses CDMA technology to send data over
the airways. AT&T uses GSM. The two radio technologies are not
compatible. It would be practical for Apple to make versions of
the iPhone that work on one network or the other, but not both.
If you want the end user to be able to swap networks, then you
could use a radio in an external USB dongle. You'd need contracts
with both ATT and Verizon, of course.
The good news is that Verizon and AT&T are both planning to use
LTE radio technology for their 4G data networks. So in a couple of
years, you'll be able to buy an iPhone that works on both ATT and
Verizon 4G networks (separate contracts for each, of course).
