Hey good to see you're making some progress on the 8-string.
The bridge is very similar to the standard 4 string bridge CROSSED with the later 6-string all metal bridge (not the rosewood and fretwire bridge used on the hag 1 bubbletop guitar).
I can take some detailed pics to illustrate for you.
What you'd need to do is get a 4-string bridge plate - drill a two holes in it - mount one of the Van Ghent bar bridges on the bass plate (these bridges were used on Guilds also) - and then either fit 8 saddle pieces to the bridge or seven, with the one having two notches for the two "G" strings.
You'll also have to drill out the baseplate for an additional 4-strings.
I'll take some pictures and send them along to better explain
