Disc/Disc vs. Disc/drum ?

[68LSS1]

Just for the record I will be running a Wilwood adjustable proportioning valve on my set up. As far as the big three going 4 wheel disc is it possible to have anti lock on drums? I'm thinking it's because it allows for better abs control. I know that abs can be had on the backs of vehicles using drums but both were controlled together via a sensor in the differential, instead of independently like the front.
