Stronger axles while retaining 4WS?

I know that you can just delete the 4WS system and upgrade to 4bolt rear end and axles from a 1G DSM (did that in late 90's on prior GVR-4). I was thinking about getting another GVR4, but I actually just won an auction for a 3000GT VR-4 Spyder. So, this is more of a "what if" question to see if anyone was able to do upgrades without losing the 4WS. One possibility I considered was seeing if the axle shaft itself could be replaced (between the existing CV joints) with a stronger one (from 4 bolt rear end, or aftermarket) rather than replacing the entire axle.

The internet is void of information it once held. Pretty should you could get a 3Bolt LSD with AWS. As someone who recently got rid of AWS, I feel like it was more of a gimmick than something that was actually needed. Near the limit, it was my understanding that AWS could cause snap oversteer. Either way, I'm fine without it and I don't want it back. After all these years, it's just a failure point. I say, let her go.

You can keep 4WS with a 4 bolt (after all, 90+ Evo Spec GVR4s had a 4 bolt and 4WS), you just need to utilize the stock gvr4 3 bolt housing. Swap the 4 bolt diff guts and everything into it. Mitsuturbo runs that exact setup and made a thread 13yrs ago on it. He's also resealed his 4ws in recent years, which negated mostly custom made seals to rebuild it as none of those bits are available either.
