One way people do stuff like this is in the %post section write commands to
a file that gets run when the live image boots up. You can probably do
what you want there. Then you would have a custom ks file instead of
a custom rpm.

Yes: 'sed -i' is your friend here.

If you install spin-kickstarts and then look in /usr/share/spin-kickstarts/fedora-live-desktop.ks, you'll find some examples.
