I prefer to think of it as alternate histories set in the same background.

I think that's just how epic is . No/very few lists have unique/'iconic' characters in them (emperor's champions are not 'unique' characters), epic is a level of abstraction above that – but nothing stops you saying that your deamon prince or bloodthirster is Angron. The space marine chapter lists are not lead by their chapter masters, but you are free to modle your supreme commander marine as Marneus Calgar if you wish.

Or one could see them as some sort of avatar for their daemonic selves. A huge lumbering war machine with the spirit of the primarch..

Yep, in which case, name your bloodthirster Angron or make up house rules of your own I agree with you though, I prefer the massive lumbering daemon spirit primarch to the liltte one

Draccan: There was a discussion about making diverse profiles for Daemon Engines of Khorne in the NetEA Chaos board, but too few people were in favour of making the change, so the proposal was dropped.
