Rather than taking time out of your day to respond as a jackass, either respond in a helpful manner (perhaps directing him to sites/forums with helpful info) or find something better to do with your time. He's come on here looking to gain information to reach a goal, not to put out an idea and have people tell him he's a moron. It is quite do-able and he obviously wants to spend the time and money. Just cuz you wouldn't doesnt mean we should all follow your lead.

If you want to say it's not worth it, simply warn him of a possible/approximate cost of doing it and let him decide if it's worth it.

Now back to the subject. In terms of your axle strength issue, and since your doing a lot of custom stuff anyways, make your own. Measure up your current ones, and find out how close they are to the ones for the civics or whatever. Make sure they're built the same (spline's and such) and customize your supension/drive components. The CV's could be extended or manufactured from scratch to fit your car. Alot of 4x4 guys get custom driveshafts, I don't see why it can't be done for an import.

Another posibility could be some kind of adapter in the hub or transmission. Very custom and in need of a professional with some killer tools, but i think it could be done.
