Sounds like a lot of work! Before you embark on some costly and labour intensive fabrications I'd be checking the rule book for your target race series to see if this sort of thing is allowed. I'd also try nudging the organisers to see if its likely to be outlawed in the near future.
Will your car be spaceframed? The reason I ask is because if you want to start swapping out the 1/4's and the roof you may upset the structural integrity of the shell.My regs are free on bodywork as per blue book so as long as it is no longer than 100cm out front to back and max width of the wing mirrors I can pretty much go to town on her!
I'm not allowed a space frame but will have a 10 point frame attached to the shell at the turrets, 4 on the floor, the last four are split stich attachments 2 at the screen pillars via swaged plate and 2 at the b pillars again via swaged plate, essentially the cage and the car become one and all the sheet metal can be replaced.
The crush zone needs to be intact, not because of rules neccessarily, but to enable support of the seating and lower frame, this also ensures the strength of the car via length and width remains in tact.
A lot fo this has been learn as you go, I know so much more than I did 3 months ago before I took my National B and swatted up on the MSA regs. My race series ahve also confirmed that 2015 will remain the same, no minimum weight limit!
