[CentOS] How to simulate minimal ISO install using stage2 image file?

I'm working on a project which automates creation of EC2 AMI images.
To do this, you must use a running EC2 instance to mount an image file
in a chroot jail.
My problem is that I want to create an AMI that looks exactly like a
minimal (nothing selected) install from the CentOS ISO image, but the
"stage2" image  file is much more "minimal" than that. e.g., it
doesn't have yum, groups, devices, networking, etc set up as you would
if you had run the ISO minimal install on a real or virtual box. I
can't mount the ISO directly in the chroot (as far as I know, but I
could be wrong).
My question is, how can I make the mounted stage2.img chroot jail look
just like a minimal ISO install? I could manually create everything
(which I have started), but this is a lot of work, and I'm likely to
miss something that an ISO build would have (e.g. some group).
Is there some other standard CentOS script I can run after mounting
the stage2.img which will do everything the installer does? Can I run
the installer manually with some kickstart script? Pointers to
references and documentation are welcome...
