There are very few files that actually contain IP numbers, viz. /etc/resolv.conf, /etc/hosts, /etc/networks and /etc/init.d/network and the first of these would probably stay the same as we're talking subnets. So all you need is a few scripts hacked from the last, that delete the two (network and gateway) routes, ifconfig the new number, and add the two new routes. They could meanwhile overwrite the middle two files as well. ifconfig and route commands are totally dynamic; I don't think daemons etc. should hold onto any of this information. (I don't have a clue what reads /etc/networks though I suppose you could use it yourself to delete the appropriate -net route.)
