I did this to my car years ago, and just recently swapped to unmodified 5 lug hubs. I wasn't confident that the drilled out knuckles would be able to take a hard hit (pot hole, bump, etc...). I'm going to run my evo suspension with 12mm bolts and spacers for the time being, once I get the bugs ironed out of the car, it's getting coilovers.
If you want my drilled out hubs, pay for shipping and they're yours. You'll need new bearings, and the big circlip that holds the bearings in.
