I'd be less inclined to start swapping parts from one banana arm to the other. If your wheel fits on the new hub w/o machining I'd leave it alone. Then the only problem to solve would be an axle with two different styles of CV joints. I don't know if all CV's are splined alike. If not, you'd need custom manufacture axles to accomodate potentially the different splines.

Experience has also taught me when you start mixing and matching parts, the axles may not be the correct length to connect the old gearbox to the new banana arm. My experience (not with a Porsche) is that the suspension will cease to function in either bump or droop, or both, if the axle is too short or too long for the application.

Don't want to be a wet blanket here, but be careful regards the axle install. I guess my question would be, "Does the aluminum arm mimic the steel arm in the arc of the CV flange through the entire range of motion?"

I know someone out there can answer better than I.
