Was reading up on the civil war on UESP, and it seems there was much content started development with material left in the game that never made the final cut. For instance, the ability to change sides depending on the result of Season Unending, the set-piece Whiterun/Solitude/Windhelm style battles in each hold capital, the chance for the final battle to occur e.g. in Riften/Markarth as Solitude/Windhelm could be won beforehand, a more active war with defensive as well as offensive battles, etc. Would it be possible to mod some/all of this into the game?
