As a long term solution to malleable transactions, wouldn't it be possible to modify the signatures to be of the entire transaction. Why do you have to zero out the inputs? I can see that this would be a hard fork, and maybe it would be somewhat tricky to extract signatures first (since you can sign everything except the signatures), but it would seem to me that this is an important enough change to consider making.
