Have you checked the CCC for your truck? If not you are likely to need more than just stiffening the frame and that 4WD conversion is just going to add more weight.
It took me a while to find it but Max Payload for the Crew Cab Dually Long Bed 2x4 appears to be 5355lbs and the 4x4 is 4910lbs. My camper according to the tag on it weighed 2906 and that included 50 gallons of water and 20lbs of propane. Going to a 4x4 conversion that would leave me 2000lbs for people and gear which would be way more than we would ever carry.
Being frank, the 4x4 conversion is something on the nice to do / want to do but not the need to do chart. Finding a good shop and a reasonable price may be the death of the idea. This goes for the frame boxing as well.
Getting back to the porpoising... I think the most realistic plan forward is to do what I can to move the camper for the extra 2". It may not help a ton but it is better than nothing.
