Depending on the situation, there are some as-builts where straight (minimum) 1/2" dia. x 12" long anchor bolts were set into the foundation concrete through the bottom plate with special epoxy. The anchor bolts were basically threaded rod so the end would fit in the hole that was drilled. I think they were primarily concerned with lateral shifting and not wind uplift. That was to bring an as-built up to code to get a permit. They also added Simpson ties between the bottom plate and the stud, the top of the stud and the top plates, etc. all the way from the foundation to the roof peak at 4 feet on center. They had access to the framing, though at that time which may have made installation easier.
Is there enough room for a Hilti gun to fit between the sill and the floor? Hilti guns are almost a fun way to install things in concrete. I've also seen some sizeable angle head drills, but for drilling in concrete a hammer drill is preferable and I dunno if they make angle headed hammer drills.
If you are concerned enough about the structural integrity of your house, you may want to consult a structural engineer to get specific and valid information for your house. Adding the brackets would be a good thing, IMHO, however my opinion isn't educated to the level of an engineer's so if you want a more valid opinion, ask a licensed engineer.
