I can recommend the -G kit, too, I built 2 of them years ago, when I was in high school. The -G originated with Monogram, by the way, and through the merger of Monogram and Revell, it's still in the catalog. You can build it into a nice model right out of the box, though, as you've seen, you can go to town and really superdetail the heck out of the kit.
I have 2 of the -F kits, which I'm backdating into -E's, for a Battle of Midway collection. The -F also originated with Monogram, in that Revell copied the Monogram B-17G, modified the nose to remove the chin turret, and then brought it out on the market. The company execs at Monogram examined the Revell kit, and sent Revell a letter to indicate that they could sue and win, but chose not to, and that it should never happen again. A little bit of kit lore there for you.
The -F is a definite opportunity to exercise your scratchbuilding skills.
Looking forward to seeing your build!
