Thanks to everyone for input, greatly appreciated!
To clarify my thinking.
This will only be a street car so i am not overly concerned about any extra weight added by this approach. As well, i only need it modular once. When completed it can be fully welded and never has to come apart again. I'm thinking that the structural requirements needed to just to hold things true until fully welded vs a modular design meant to be disassembled in use are different (hopefully lighter)?
My goal is to be able to complete each section independently in a small space. In my large shed i can setup a build table of about four foot by four foot at the biggest with enough room left to get around. Lots of smaller shed space to squirrel things away separately. No shed big enough to do the complete frame in. The pic below shows what i was hoping to accomplishment:

It seems the bulk of the project is working out everything in what i call modules 1 and 2. The tricky part of the build for me will be sorting out the suspension geometry and wishbones. This is what i would like to accomplish this winter. The suspension bracket labeled in the picture below makes splitting off module 1 awkward (sorry for the mix of Book frame in one pic and Collins in the next, at this point i am thinking a Collin's style frame with Book dimensions).

If i'm understanding the sequence suggested by Lonnie-S it seems to be a great way to make the frame up in parts but doesn't really give me the ability to 'complete' each section independently? Will study more.
That 'shop' view for Shevalez is something else. I could make the frame in my living room and get it out the picture window, trying to convince my wife is something else entirely!
C10Corey, I see you are in White rock, any chance i have seen your car on the Sea to Sky? Seen quite a few 7 variants on there this summer (i live in Squamish and commute the Sea to Sky daily).
