You could probably wrap something up to do that with some scripting.
Why are you editing the cpio by hand?
You could do all your customization in a post build script.

Well, you're somewhat light on details so we're left here to guess.
One possibility is that your dnsmasq package has dhcp support disabled,
another possibility is that your wlan0 doesn't belong to a proper
subnet/hasn't got an ip address configured at all to match that range.
Again, i can just guess without some proper information.
