iPhone Swapping: A SIM is a SIM is a SIM?

Two iPhones, a 2G and a 3G, on a family plan. Adding a third, a 3GS. Can I just swap the SIM cards to get the phone numbers onto the devices I want them on, or does AT&T need to get involved?

The scenario: I have two iPhones on my current family plan (actually, three, but one isn't going anywhere, so we'll leave that out of the equation). There's a 2G my wife uses, and my 3G. Miraculously, the 3GS comes out just when I started phone shopping for my daughter.
I want to get a 3GS, then "bounce" the SIMs/numbers down the line. In other words, I want the 3GS, my wife would get my current 3G, and my daughter would get the 2G. But my wife and I want to keep our numbers, and give the fresh, new number to my daughter.
In the shuffle, the new phone number SIM that comes with the 3GS would go into a 2G phone, the SIM from the 3G would go into the 3GS, and the the 2G SIM would go into the 3G. While the 3G and 3GS seem to be identical as far as AT&T is concerned, the 2G has a different plan/data with AT&T that's cheaper.
Provided all phones, including the new phone, are properly activated and running with AT&T, can I just put the SIM cards for our respective numbers into the phones I want them to be on?
My feeling is, since we'll still have the same mix of 3GS/3G/2G SIM cards running, it should all work out in the end as long as I pay. AT&T shouldn't care which SIM is in which phone. But, maybe not. Is there any need to involve AT&T in this merry-go-round, or is a SIM a SIM a SIM?
