I guess we'll have to be patient for DPII to reupload. I am itching to use it though -- my brain is already concocting new Traits I want to make using this modcomp, as well as changes to existing Traits... 
Hmm, well, I'm afraid I don't really know how to do that either.
I'm only really XML capable, python incompetent (or worse), and SDK incapable. Your plans still sound interesting and potentially useful though, regardless of whether I'll be able to use them in the way described.

There isn't a direct way to implement the promotion via Tech which I know of, but you could make an event which requires that Tech and has a -1 Weight which provides the promotion to all units.

I've been holding off on some of my own modding hoping that this would get re-uploaded and was almost to the point of just attempting it myself
become 6
becomes 10 :food) , but not provide anything if you do not gain yields from combat (so if Combat 5 was changed to provide +300% Commerces, but you didn't have any promotion to provide you with commerces from battle... you'd not notice any difference from normal Combat 5)
And I think that almost half of those are from me clicking on it and hoping 
, I'd like to allow that one to be used, and make it split based on the current slider settings. I think I see how to do it, but I haven't sat down to take the time for it quite yet.
At least, I'm not having any success with it so far. Is there any possibility of getting a standard game modcomp, ala DPII's original but with the promotion fields included?
