At only 8", missing rebar (or drilling through it and removing any sort of interaction between the rebar and anchor), etc. is going to be really hard period much less getting a sufficient moment arm to resist your 8.4kip-in (+/-) moment.
I would say that depends on the kind of wall that we're dealing with. I was assuming a lightly reinforced retaining wall. Maybe two layers of #5 at the dirt side only or something like that.
One trick for increasing the likelihood of the post installed anchor setup being able to handle the moment is to take advantage of the fact that there will be a base plate compression block pushing down right next to the anchors that are trying to pull up. That will tend to alleviate pullout and make it more about direct shear and pry out.
There are very few situations in which I'm a fan of through bolting. That, because:
1) As far as I can tell, there's no accepted way to design those connections except for some weird CMU shear wall tech notes floating around out there.
2) Also as far as I can tell, most things that you could to with a through bolt could be done as well or better with an adhesive anchor. Most of the action happens near the concrete face in both cases.
3) Too often, through bolting seems to be used as an excuse to ignore concrete breakout failure modes.
Conceptually, I like the saddle setup but, as with the through bolts, it takes an annoying level of judgment to "design" such a connection.
