The easiest way to do that, that I'm aware of is to reflash back to your stock ROM, you did a NANDROID BACKUP didn't you? And pull the .apk's you need off your phone. Then flash your new ROM and push all those .apk's back to your phone. The thing is though if you do that you aren't using Jager anymore you're using the stock RO so it kind of defeats the purpose. Not to mention fighting force closes till you figure out whatever you may be missing.
My suggestion to you is reflash the stock ROM and just remove what you don't want or need.
