Generally speaking...."maybe".
I did this and at the end of the day, it did not work out for me. I swapped over the 6-lug axle shafts and the 6-lug backing plates (with drums).
Everything came together nicely but the drums rubbed on the backing plate when I spun the wheels. It was "SO CLOSE" but rubbed just a little. After looking into it further, I think there are a few different lengths of axle shafts and a couple that were only a few fractions of an inch difference. So maybe that was my problem. I looked on Randy's Ring and Pinion for different axle shaft lengths.
You might get lucky and get the correct clearance......just don't know. Everything did go together well, I was just a fraction too short. I probably could have added a very small spacer between the axle shaft and the brake drum to make it work but I'd rather have one complete, working one vs. piece-mealing it together.
Just my experience and others might have made it work without any problems.
I was also aiming towards the more narrow axles (2wd models) so the wider axle may be different as well.
