I hacked the Radavist hack for a Decaleur using the Thomson direct mount stem, some rack hardware (from Tubus and Surly) and instead of the Ortlieb hooks I used Lone Peak Pannier Hooks (thanks to Wayne at the Touring Store) and those have worked great. The nice thing with the Lone Peak hooks is they lock on and have provided a nice sturdy fit with no wiggle or jiggle. I used a stock Nitto M12 rack so I cannot speak to using alt racks but so far it has been a quite solid set up. I wish I had done a little different hook mounting on my rando bag from Swift Industries but I could easily fix it with a different backer (using an old plastic political/ad sign that was littered on stakes in the median) that didn't compress as much.
