That will be one serious bit of kit if you pull it off, but it will be a bit like trying to fit a size 10 foot into a size 8 shoe. If you manage it, there probably wont be any Nova left.
Wouldn't it be easier to build the thing from scratch spaceframed and pop a nova fiberglass bodyshell on top?
Dont take these opinions to heart though mate, when you start the project, we'll all be rooting for you!
