Hey Thomas, As mentioned by Tonya nd Joseph, the Blaster most likely will not be approvable on the pack. As far as the strapping I do the same on my pack as Joseph stated. I have a 1 inch webbing with quick disconnects that goes under my shoulder bridges and connects to the bottom corners of my packs. I've cut grooves in the plastic and looped the webbing through. Also, the pack you build looks awesome, great job!
