Going by all this, the actual axle stubs are completely interchangable. Just be aware of the inner axle flange and the bearings.
The way I read it, to do a 4 to 5 lug swap, all you need is the 5 lug axle shafts (with the grease catchers and wheel studs) (part number 38162-02P01 x2) and the appropriate 5 lug rotor (part number 43206-02P01 x2). Of course, since you're pulling everything apart, it would be a good time to inspect and possibly replace the bearings and install with new oil seals and grease.
