This comic is more Fear Agent or Prophet or Heavy Metal than Captain America. Though it's a daring idea, I'm not sure it's an entirely successful one. The resulting story is unfortunately very slow moving and doesn't have a lot of emotional resonance once it's removed from the real world. 
 I also found the artwork problematic. I usually love Romita Jr., and I think his artwork is very well suited for this story. Unfortunately, he doesn't seem to know how to draw children, and there are lots of them, both in flashbacks in the modern-day, and that unfortunately knocks me out of the story. 
 So, a noble experiment, but not an entirely successful one.
