Sleaving large-bore pipe for added streangth?

Where does the president keep his armies?
In his sleevies.
Has anyone tried sleeving larger diameter pipe? My idea is to sleeve a solid piece of 4" sch 40 into a piece of 4" sch 40 that is sliced lengthwise down the center on a table saw. It will leave a gap, but over all, it should be considerably stronger. Is the gain worth the effort? Would it be stronger than sch 80 for a hybrid design?
I was also thinking about sleeving some 2 1/2" with 3", centering it with spacers and filling the gap with spray foam (the non expanding stuff for windows and door jams). I know this would be strong but I would prefer a shorter, wider chamber to a longer, narrower one.
One last thing. Would using small screws at the joints increase or decrease the over all stength of the joint?
