http://forum.paradoxplaza.com/forum/showthread.php?716282-Improving-non-Norse-and-non-Mongol-pagans talking about giving altaics prepared invasions. I don't know how crazy or flawed my plan is but read my chunk of paragraph in my thread about how it MAY be possible to have eastward movement of tribes, I'll just copy/paste
great idea, prepared invasions turn off at 40 realm holdings, maybe have an option like the magyars to "drop the east" to be able to invade richer western lands. but you should be able to invade then drop the lands of the kingdom you once had... hmm... maybe this can be modded in like the Hungarian invasion to have tribes moving westward.... Hungarians move west drop the east and the pechenegs do something similiar.... but how to make it so the ai has the tribes pushing westward from the far east...? maybe allow count level vassals of different cultures(say the pechenegs are subdued by the cumans) have the option of re-setting up the tribal kingdom of pechenegs and invade the west so you can free yourself from the Cumans... the last problem would be culture shifting... maybe all altaic cultures can shift quickly within the altaic group meaning a pecheneg invasion into Wallachia will convert the Avars and Cumania into Khazaria/Pechenegs will convert them to Cuman.... this may all work...
on top of this, you can tie this in with the de jure system so a pecheneg vassal in de jure outside his Khan liege (aka pecheneg vassal under Khazarian Khan of Khazaria but the vassal is in Taurica) only that Pecheneg could invade westward and not all of them.
And indeed you may want to throw in some ai only stuff and let the player invade eastward if they so desire.
EDIT: I was jk about the drop everything btw

but tell me what you think if you ever plan on going back to the steppes
