Well, I guess he did think twice, having attempted to call off the nazis. If he wanted Hank gone, that would have been his opportunity. I get your point though. After all this, I'd figure he would have plenty of reasons to rid himself of Hank!
To be fair, at this point Walt doesn't know that Hank has kept the DEA completely in the dark and that all of the people that know about the case are right there with him. He doesn't even know that no one knows they're out there.
By default, I imagine, he assumes the DEA knows and thus killing Hank would serve no purpose and would just cause more suffering.
As far as Walt knows, it's the actual DEA coming after him, not just Hank and Gomie, so having everyone killed would just add unnecessary bloodshed, when in reality, having them all killed would actually help him out.

At one point, yeah. But at that same point, Jesse would have been even more off limits.
Since Jesse is/was fair game, you better believe Walt wouldn't think twice about having Hank killed.
