RDO Packstack does allow to do that . See http://bderzhavets.blogspot.com/2014/11/rdo-setup-two-real-node.html
Just skip all Gluster integration part.
However, you will pretty soon realize that having Storage on Controller or Compute ( not like a separate node ) is not the best idea, unless you want just POC ( proof of concept ).
I don't won't put any pressure on you right now, you would see it for yourself.

As far as you would like Swift work as Glance backend or simplest iSCSILVM backend for Cinder performance issues be be right here,so you would need storage node badly. Kudos to RH packstack allows to add Storage Node to landscape just tacking care of keystone endpoints for glance and swift onhttp://bderzhavets.blogspot.ru/2014/11/rdo-setup-two-real-node.html your own.

You last notes remind me TripleO Setup with
1. Undercloud deployment
2. Overcloud deployment
If you believe that Heat and puppet Openstack are already in your area of expertise. It would work for you even better than packstack ( 3 Nodes at least , sorry). No one of approaches suggested ( on CentOS 7.2 ) don't require any licensing ( just stay away of RHEL 7.X )
