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.
Well, I am all for costly respecs, but my point is that they should give one for free early on for players who messed up at character creation because they didn't know the rules. ^^
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^^.
I know, I was referring to when the game is released.
