Hey if someone wants to try it I'd like to see it. But there are a TON of potential issues. And honestly, when you're all done, you may not have a car than handles any better than one with a well tuned torsion bar suspension even if everything works great. Because really, a well tuned torsion bar suspension is no slouch. The current coil over conversions aren't demonstrably better. The Hotchkis Taxi can lap at TireRack's test track faster than the 2012 3-series beemers they use for testing. That's a ton of work to undertake on a "maybe", even if you have all the skills. I do, I have both the skills and equipment to make that happen if I wanted to, and let me tell you I have zero desire to do it. If you spent a fraction of the time and effort needed to complete that swap you could have a very well handling torsion bar suspension car.
