This rather large update is thanks to Macattack. I saw in his MkVI thread that he was using a different method to attach the front sections of his boots to the main body. I originally wanted to do something like this, but was unable to find the type of buckles that would work. Well, Mac pointed me in the right direction and yesterday I found these...
These center button quick release buckles are the perfect size to fit into the side of the boot armor. So, thankfully disassembling the hook/bolt system, I set out to install these buckles today.
First, I took the female end...
...and snipped off the part that where strapping would normally connect...
Then, I traced the profile out on the side of the boot...
...and cut out the corresponding sections...
...then tacked the female end in with a few drops of hot glue.
After that, having learned a little from Cereal Killl3r, I boxed off an area surrounding the buckle from the inside...
...and poured in some thin, quick-setting rondo...
...and when the rondo started to harden and heat up, I removed the blocking and what hot glue I could...
When I removed the masking tape from the outside, I found that the rondo had been masked nicely...
...so I applied some bondo to the outside and started to shape it up a bit...
Now it was time to connect the front end to the male end of the buckles. Originally I was going to attach the male side to the inside of the armor, but I realized that it would line up better if it was inset into the armor itself (much like the female end is)...
...so I traced the profile and cut out the corresponding part again...
Holding the front part in place, I tacked the male end on with some hot glue and carefully removed the male end from the female end...
...then I added some more hot glue to secure it...

That is as far as I got tonight, as I worked until sundown. Tomorrow, I will apply some bondo to the interior and exterior of the front armor piece in order to better secure it into place.
Overall, I'm pretty happy with the way this is turning out so far. And it looks a heck of a lot better than it did before. Once I get the front piece bondoed, it will be difficult to tell that the buckle is attached the way it is. So, thanks Mac!
