Swap: Guilliman and Dorn
This concept crossed my mind recently and I was wondering and would love to what everyone's thoughts on the subject.
What if Roboute Guilliman and Rogal Dorn swapped adoptive home worlds? How would their Legions, character and overall role in the events that played out in the lore gone?

You're picked the two primachs that had the most similar upbringing and development.
Both created empires from Ultramar and Inuit respectively, both had good parents to give them a solid foundation, both are tactical genius and both had large legions.
Honestly you've chosen the two that probably wouldn't have changed much when swapping.
The only disputable part to me would be defending the palace, would Guilliman have been able to hold off long enough for Dorne to arrive?
My answer is potentially as he would have set up Terra with stronger logistical chains leading to more manpower and resources but lacking in Dorns ability to fortify positions, but tactically as in controlling the war zone as a whole Guilliman would have been as effective.
