I really like the idea set out here but unfortunately it's pretty much guaranteed that if they were to implement something like this it wouldn't be until a later content patch after release, the reason for this being that at this late stage in the development they are almost certainly going to have their game set to 'feature complete'. Particularly now that they've announced a release date for the game, these last couple of months leading up to release will be spent looking for bugs, balance changes and maybe a bit of optimisation where it's needed. But, like I said, I think that this idea could have potential and I hope that the talented team at Paradox sees it!
