Just out of curiosity, since I've never done this sort of thing before, if it is only the roof that's damaged (and not the chassis *crosses fingers*) how much do you think a fabrication shop would charge just to replace the entire cap? Not the whole shell just the cap that starts at the top of the windows.
Sorry to say this but I think your best action would be a salvage operation and use the money to buy another bus. RUST NEVER SLEEPS! I fear any cash you invest in this project will be throwing away good money after bad. The money to reskin is money that could be going in to your conversion.
Also, I can almost guaranty you that the chassis is not much better. Just climb under the bus and you can see for yourself.
