I guess i can understand the desire to try to swap things around from a "this would be a fun project to occupy my time" perspective. From the perspective of a swap that is worth the time and money, I don't understand it. 44's aren't substantial upgrades, and 44's that require a ton of extra labor to swap, aren't worth the time.
If you're doing it to "take it to the next level", then don't. If you just like to tinker with things and like the idea of getting hubs and a stronger ring gear (but don't plan to go with bigger tires), then by all means get after it.
