Larian allowed the respec in DKS - which was however pretty expensive. In one of the Twitch TV streams Swen said something like "they allowed it in previous games so there is no reason to not allow it in DOS". So, my guess is you will be able to respec your character at some point but it will also be very costly.
As for your particular problem: The savegames will be probably broken again with the next beta update so you will be forced to start anew anyway^^.
