Well, if money/availability is no object, you shouldn't be using any enhancements, only optimization.
Next, come on, get is reaction up higher. Reaction Boosters, level 3. Since we are looking for something that is as close to -6E as possible, we can get his reaction up to an augmented maximum of 14 of 15.
Since we are talking about a super zombified guy, get rid of the synaptic booster. I know that it is great, but don't get it. Instead go for a move by wire system at rating three so he gets skillwires and a dodge bonus.
This isn't everything, but I was working on a cyberzombie for under a million.

It handles most things well, and like I said, the goal was for under 1 million nuyen so it could have a potential military application.
