The banter really isn't anything special, it was basically a test. You're missing out on about three conversations per pairing at most.
The patch you're asking for is also kinda redundant because the Core files of ezPG already contain the up-to-date version of all three followers - Nessa, Eris, Dzarkim - Citizens with the option to disable all of them, plus Teleportation Cubes.
TC is a tiny, tiny gameplay mod that doesn't warrant making another plugin version in xEdit. There's nothing else that comes with Core. Emberveil has to be installed as an extra option and a separate plugin.
