the problem stems from the high lords themselves though, as well as the current state of the imperium: the high lords have ruled the imperium for 10,000 years and every person in a posirion of power wants to maintain that position of power. so they would be very reticent, at best, about handing over such power to any returning primarch, even guiliman.

any returning primarch will be made very aware of just how far the imperium has devolved from emps' vision and i would think that every loyal primarch still alive that returns will almost immediately set about trying to alter the state of the imperium to more closely resemble what emps was attempting. this attempt alone could easily be enough for the high lords to brand any returning primarchs as heretical or to even slander them as being sent from the chaos gods to destabalize the imperium.

i fully believe that the single biggest obstacle for any returning primarchs is the very possible potential of the high lords to label them as enemies, which would result in another galactic civil war.
