I dont know if this subject has already been discussed, but does anyone know of a kit or conversion package to change an 800 series 5 ton to air brakes? Is it simple or not worth it? I tried several times to buy wrecked 900 series trucks to just swap them, but even they go pretty expensive.

Do you know which axles you have? If they're the same as the M900 series trucks the backing plates should bolt right on. If not, swapping axles might be the fastest although no necessarily the cheapest. Remember too that you'll have to get an E-7 treadle valve (brake pedal assy), relay valve and a couple of quick release valves for the rear axles and possibly a limiting quick release for the front.
Go to Bendix's site and download the "Air Brake Handbook", available in .pdf format and read up on the differences of air over hydraulic vs. full air brakes. Also check out the "Air Brake Components" handbook at the same site to get a description of the various components. I'm putting full air in my baby HEMTT project truck so I'm a few months further ahead on the same stuff you're contemplating.

Memphis equipment did a bunch of civi s cam brake conversions to 5 ton trucks so the parts are out there but i don't have part #'s. in my opinion the s cam style really hang in a bad spot when fitted to the 5 ton Rockwell's. the wedge system fits way better as far as keeping the components out of harms way. there will be those that disagree but the wedge system is far superior as far as braking power, just a pain in the butt to adjust.

I know Clark Truck converts 800's to full air. It would be top dollar with them though. http://www.clarktruck.com
