First off, the sub-frames are NOT the same between 71 and 67 and they do not interchange. As far as swapping components over, that is a big MAYBE! I've not heard of anyone trying this so I won't say it can't be done, but some things to consider. First, the 71 frame is supposedly wider than the 67s so you might end up with your wheels sticking out too far. Second, I don't think the a-arms will bolt in the 67 brackets, there are slightly different designs. Also, the 71 uses taller spindles, so there might be an issue there, depending on if everything else fits.
I've seen where people have tried to swap in the whole later sub-frame, but it took extensive work. I have also seen a lot of people that have switched to the taller spindles, but have used the stock a-arms and such. Personally, I think someone should try what you are suggesting and see how it comes out. Maybe you are on to something...
Good luck and keep us posted if you decide to try it.
